Question

What is the constant in 15-8y
A 15
B 8
C-8
D -15

Answer 1

Simplifying
15 + 8y = 15

Add '-15' to each side of the equation.
15 + -15 + 8y = 15 + -15

Combine like terms: 15 + -15 = 0
0 + 8y = 15 + -15
8y = 15 + -15

Combine like terms: 15 + -15 = 0
8y = 0

Solving
8y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '8'.
y = 0

Simplifying
y = 0
