Question

could someone teach me how to solve this?
Solve the equation. show your work. check your answer.
3x - 7 =5x + 19

Answer 1

can you help us again?
@FibonacciChick666

Answer 2

Yeah sure.
see subtract 3x on both the sides of the '='

Answer 3

Add 7 on both sides -_-

Answer 4

ok, so the goal here is to have only x terms on one side, and only non x terms on the other

Answer 5

so first, can you tell me what the x terms are?

Answer 6

3x and 5x

Answer 7

ill make this a lot easier on you

Answer 8

Answer 9

good, so now, what are the non-x terms

Answer 10

enter the equation onto that

Answer 11

@skate-4-life270,
1. we are here to help not give answers. openstudy.com/code-of-conduct
2. some people actually want to learn.
3. please bug off if that is what you call a meaningful contribution.

Answer 12

sorry, @AngelofVengeance6661, what are the non-x terms again?

Answer 13

i didnt give her the answer, that site shows her step by step how to do it

Answer 14

and i know about he code of conduct youve told me it 100 time the past week, and what i did isnt violating it

Answer 15

that yields a step by step solution with no resoning nor assistance hence, just an answer

Answer 16

the non-x terms are -7 and 19

Answer 17

good, so now, pick a side. Which side do you want to put the x terms on?

Answer 18

um. right?

Answer 19

ok so we shall have non x terms on the left and x terms on the right

Answer 20

\[3x-7=5x+9\]

Answer 21

the first thing we want to do is figure out how to 'undo' the addition of the 9 on the right

Answer 22

so what is the opposite of addition?

Answer 23

-

Answer 24

yep subtraction, so to undo the addition of 9, what do you think we need to do to both sides?

Answer 25

subtract

Answer 26

subtract what?

Answer 27

wait a minute im lost o.o

Answer 28

ok so just reread the last two comments I have made, think "what am I undoing?" "How do I undo it?"

Answer 29

wait do you do this the same way you do a regular problem just with two numbers instead of 1

Answer 30

I think that what your saying is true, but I don;t know what you are saying

Answer 31

so, give me an example of what you are saying so I can see if it is

Answer 32

i understand it now. i even checked it myself c:

Answer 33

ok :) then show me your work

Answer 34

try and explain every step, you'll understand better if you do

Answer 35

3x-7=5x-9
-5x from both sides
= 2x-7 and -9
+7 both sides
=-2x and -2
divide by -2
x=1

Answer 36

yeah if your going to use an online source it has to explain the math and it has to be accurate and no wiki.

Answer 37

ah so what is 3-5?

Answer 38

ok wait, you may have it you corrected it in the next step

Answer 39

so here is how I would write it, let's see if we get the same:\[3x-7=5x\color\red{+19}\]

Answer 40

ur way takes too long

Answer 41

so our first thing is we didn't copy the problem down correctly, but let's see if you did the steps after correct.

Answer 42

@skate-4-life270 I help and teach. That is what this site is for. DOn't like it? then leave

Answer 43

ok i will

Answer 44

ok so you wrote,\[3x-7=5x-9\]
subtract 5x from both sides-I agree\[3x-5x-7=5x-5x-9\]\[-2x-7=-9\]
Add 7 to both sides, (I agree with the step) \[-2x-7+7=-9+7\]\[-2x=-2\]
Divide by -2. agreed \[\frac{-2x}{-2}=\frac{-2}{-2}\]
\[x=1\]

Answer 45

so end result, you did the math correctly, but if you do not copy the problem down correctly, you will unfortunately be incorrect
