Simplify your answer as much as possible.

-3v+18=8v-15

-3v-8v=-15-18

-5v=-33

v=33/5

.

Multiply 2nd equation by 2;

-5x-8y=17

6x+8y=-14

Then add them to eliminate y;

-5x+6x-8y+8y=17-14

x=3

then we can find y from either from 1st or 2nd equation by plugging in x;

6(3)+8y=-14

18+8y=-14

8y=-32

y=-4
