Answer:
Step-by-step explanation:
Simplifying
16 = 2y + -4
Reorder the terms:
16 = -4 + 2y
Solving
16 = -4 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
16 + -2y = -4 + 2y + -2y
Combine like terms: 2y + -2y = 0
16 + -2y = -4 + 0
16 + -2y = -4
Add '-16' to each side of the equation.
16 + -16 + -2y = -4 + -16
Combine like terms: 16 + -16 = 0
0 + -2y = -4 + -16
-2y = -4 + -16
Combine like terms: -4 + -16 = -20
-2y = -20
Divide each side by '-2'.
y = 10
Simplifying
y = 10
