y = 3/4

Step-by-step explanation:

Given two equations

-3x+2y = 7 … (1)

-3x-2y = 4 … (2)

Subtracting the second equation from the first will give us;

-3x-(-3x)-2y-(+2y) = 4-7

-3x+3x-2y-2y = -3

-2y-2y = -3

-4y = -3

y = 3/4

The result of the difference between the second and the first will give y = 3/4
