4y + 10 - 2y = 8 + y?Take the "y"s to one side.
4y - y + 10 -2y = 8
Simplify.
4y - 3y + 10 = 8
y + 10 = 8
Take the other numeric values to the opposite side to your unknown value.
y = 8 - 10
Simplify.
y = -2
4y + 10 - 2y = 8 + y?
4y + 10 - 2y = 8 + y
4y - 2y + 10 = 8 + y
2y + 10 = 8 + y
2y - y = 8 - 10
y = -2
