Answer:
y = -5
Explanation:
You want to solve for y in 2y -3(2y -3) +2 = 31.
Simplify
Parentheses can be eliminated using the distributive property.
2y -6y +9 +2 = 31
Like terms can be combined.
-4y +11 = 31
Solve
We can separate the constant and variable terms by subtracting 11 from both sides.
-4y = 20
The value of y is now found by dividing by -4.
y = 20/(-4) = -5
y = -5
