no solution for such a problem when the variables cancel out and leave you with something like 5 = -6
so first try solving for the variable for each option...

I could never do these

jigglypuff314 · Answer

so let's start narrowing our options down:

7v+2=8v-3
v = 5
so there is a solution therefore it Can't be A

3x-5=3x+8-x
3x-5=2x+8
x = 13
so there is a solution therefore it Can't be B

A. 7v+2=8v-3
   -8v     -8v
-v+2=-3
    -2   -2
-v=-5
v=5
