8(9+y)-6(y-12)=0

Solution for 8(9+y)-6(y-12)=0 equation:

Simplifying
8(9 + y) + -6(y + -12) = 0
(9 * 8 + y * 8) + -6(y + -12) = 0
(72 + 8y) + -6(y + -12) = 0

Reorder the terms:
72 + 8y + -6(-12 + y) = 0
72 + 8y + (-12 * -6 + y * -6) = 0
72 + 8y + (72 + -6y) = 0

Reorder the terms:
72 + 72 + 8y + -6y = 0

Combine like terms: 72 + 72 = 144
144 + 8y + -6y = 0

Combine like terms: 8y + -6y = 2y
144 + 2y = 0
