y=
= 0.75
Step-by-step explanation:
To subtract the second equation from the first equation, you have to divide the equation as left of the equal sign and right of equal sign then do the calculation separately. The calculation will look like this
-3x +2y = 7
-3x - 2y = 4
_____________ -
(-3x +2y) - (3x -2y) = 7 - 4
-3x + 2y + 3x + 2y = 3
4y= 3
y=
= 0.75
