Solution for 9(z+4)-2(z-4)=(2-3)+(2-3) equation:


Simplifying
9(z + 4) + -2(z + -4) = (2 + -3) + (2 + -3)

Reorder the terms:
9(4 + z) + -2(z + -4) = (2 + -3) + (2 + -3)
(4 * 9 + z * 9) + -2(z + -4) = (2 + -3) + (2 + -3)
(36 + 9z) + -2(z + -4) = (2 + -3) + (2 + -3)

Reorder the terms:
36 + 9z + -2(-4 + z) = (2 + -3) + (2 + -3)
36 + 9z + (-4 * -2 + z * -2) = (2 + -3) + (2 + -3)
36 + 9z + (8 + -2z) = (2 + -3) + (2 + -3)

Reorder the terms:
36 + 8 + 9z + -2z = (2 + -3) + (2 + -3)

Combine like terms: 36 + 8 = 44
44 + 9z + -2z = (2 + -3) + (2 + -3)

Combine like terms: 9z + -2z = 7z
44 + 7z = (2 + -3) + (2 + -3)

Combine like terms: 2 + -3 = -1
44 + 7z = (-1) + (2 + -3)
