Answer:
y = 2
Explanation:
First you need to get rid of one of the variables so you need to move it to the other side of the equation. When you do so, the sign changes and becomes either positive or negative so
if we move y it will be like this
(3y - 3y) -4 = 6 - 2y - 3y 3y became negative
-4 = 6 -5y
then we do the same thing to 6 so
-6 -4 = -5y
-10 = -5y
then we divide -10/-5 = 2
so, y = 2
