Question

can some one check this
How many solutions does the equation have?
a+5=1/5(5a+25)
i think its no solution but can someone tell me if im right

Answer 1

ya me too i think its no soluton

Answer 2

a+5=1/5(5a+25)

distribute 1/5 on right hand side, what do u get ?

Answer 3

@ganeshie8

Answer 4

how did u get 30a ?

Answer 5

a+5=1/5(5a+25)

distribute 1/5 on right hand side, you get :

a+ 5 = 1/5*5a + 1/5 * 25

Answer 6

simplifying, you get :

a + 5 = a + 5

Answer 7

oh thanks

Answer 8

which is true for all "a"

Answer 9

so there will be infinitely many solutions

Answer 10

oh ok thanks can you help me with 3 more?

Answer 11

I'll try, ask..

Answer 12

How many solutions does the equation have?

4x+2(x-3)=8x+12

Answer 13

@ganeshie8

Answer 14

what do u think ?

Answer 15

i mean, do u know how to solve these without guessing ?

Answer 16

solving these is easy

Answer 17

you just need to isolate x

Answer 18

4x+2(x-3)=8x+12

first distribute 2 for the parenthesis on left side

Answer 19

what do u get ?

Answer 20

i dont understand

Answer 21

on this one i seriously dont even know to take a guess its hard for me

Answer 22

Answer 23

@ganeshie8

Answer 24

its your chance to understand, it wont take any time
u wil understand them in less than 5 minutes

Answer 25

ok lets do it

Answer 26

you need to know distributive law : ` a(x+y) = ax + ay `

Answer 27

heard of that law before ?

Answer 28

yes

Answer 29

4x+2(x-3)=8x+12

if you just want answer,
the answer is `only one solution`. but with that you and me wont learn anything

Answer 30

4x + 2(x-3) = 8x + 2

distributing 2 you get :
4x + 2x - 6 = 8x + 2

combining like terms on left hand side you get :
6x - 6 = 8x + 2

Answer 31

ok explain

Answer 32

by this time, it should be clear that there is an unique solution.
if not, go ahead and solve x

Answer 33

ok so here i tried doing this one and i got these 2 anwers do im almost shure i got them rightWhich expressions would complete this equation so that the equation has no solution?

6(4x – 3) – 10x =

Choose exactly two answers that are correct.

A.
14x – 15

B.
2(7x – 10)

C.
15x – 14

D.
2(7x – 9)

Answer 34

i choosed a and d

Answer 35

@ganeshie8

Answer 36

a is correct,
but d is not correct

Answer 37

D gives you infinitely many solutions

Answer 38

so c right

Answer 39

@ganeshie8

Answer 40

no, C gives you an unique solution

Answer 41

so b
??????????????????? how

Answer 42

@ganeshie8

Answer 43

A and B
