Question

Can someone help with 7th grade algebra? i understand, but i still need help

Answer 1

sure

Answer 2

thanks. variables and percentages are difficult fot me

Answer 3

have u got any question with u ?

Answer 4

no, im sorry

Answer 5

Then how am I supposed to exlain...if do not have any questions

Answer 6

i do! can't you just make up a problem? gooses >:(

Answer 7

ok

Answer 8

thanks

Answer 9

x + 5 = 6 ... something like this?

Answer 10

yeah. that would be 1. right?

Answer 11

ok... we need to solve for x...for this we have to subtract anything which is on left side...in this case we have 5 ...
so x +5 - 5 = 6 -5 ... u got it?

Answer 12

i think so?

Answer 13

:(

Answer 14

ok, so i just thought that you went like "Ok, so it is x + 5 = 6, so i can flip it around, to where it makes 6 - 5 = x, and the answer would be one" thats just how i think :/

Answer 15

ok so are you doing Pre-algebra? is tht wat ur school calls it?

Answer 16

yes.... i'm trying to get to just plain algebra too because i am really slow when it comes to math

Answer 17

ya same here but i rocked it when i took pre agebra all A's All year. idk why... anyways so u say u dont have a problem but im in a much bigger math class than that right now so i cant make up a problem.... so u give me one and i can help!

Answer 18

um ok.... say if it was like 4t - 6 = 27 ¿:ı somethin like that. i will brb i need to go make some food... it will take like one minute

Answer 19

ok imma rite the steps the solve that problem it EASY

Answer 20

k back

Answer 21

so the problem is 4t - 6 = 27
and ur trying to find the value of T.
The first step is:
4t - 6 = 27
+6 +6
4t = 27 + 6
^
33
4t = 33
4 4
The fours cancel out so that t = 33 / 4
^
t = 8.25

Get it kinda?

Answer 22

uh...

Answer 23

?

Answer 24

whats thr +6 +6 thinggy?

Answer 25

thats just a step u need to do so that you can find what t equals. Bc 4T - 6 = 27 so that to find t u have to find oh well nvm

Answer 26

i'm sorry

Answer 27

i'm stupid :/ i suck at ,ath

Answer 28

basically if you have b+2=3 and you want to solve to b, to get rid of the 2 on the right hand side of the ='s sign, you have to subtract 2 from both sides of the equation.
so you have:
b+2-2 = 3-2
b+0 = 3-2 = 1
so b=1

Answer 29

that makes some sense

Answer 30

basically whatever you do to one side of the equation, you have to also do to the other side

Answer 31

so if you have 2*a = 10
and you need to solve for a
then you need to divide both sides by 2 to get rid of the 2 multiplying the a,
and you end up with
2*a/2 = 10/2 = 5
so a = 5

Answer 32

¿:ı i understnad most of that

Answer 33

so could you solve for c in:
2*v +3 = 23 ?

Answer 34

sorry solve for v!

Answer 35

um yes.. so .... uhh

Answer 36

where do you think you'd start?

Answer 37

at the 2*v right? can you turn it around?

Answer 38

It would be easier to start by getting rid of the 3 on the right hand side.

Answer 39

ok. so, because it is a positive you would subtract right?

Answer 40

yep

Answer 41

so, 2*v +3- 3 = 23 ?

Answer 42

subtract from both sides :)

Answer 43

oh yeah :) 2*v +3- 3 = 23- 3 would = 20 so far right?

Answer 44

yep

Answer 45

k so what would you do next?

Answer 46

well then as you have 2*v = 20, you want to get rid of the 2

Answer 47

um would you do the same thing? but ddividing?

Answer 48

exactly. divide through on both sides.

Answer 49

k so... i'm sorry i suck at division. whatt would you divide by?

Answer 50

so because you want to get rid of the 2, you divide through by 2. ie:
2*v/2 = 20/2

Answer 51

does that make sense?

Answer 52

yes.. but why would you keep the *v ?

Answer 53

i'm sorry :/

Answer 54

you are solving for v, so you want to end up with v on one side, and everything else on the other side of the equation.

Answer 55

oh. so... you would end up with 1 right? but on the right side it would be 10.

Answer 56

yeah, because v*1 = v :) so v = 10 is the answer

Answer 57

sweet! thanks (:
