Simplifying
-1[7z + -1(16z + 9)] = 9 + (8z + 0)

Reorder the terms:
-1[7z + -1(9 + 16z)] = 9 + (8z + 0)
-1[7z + (9 * -1 + 16z * -1)] = 9 + (8z + 0)
-1[7z + (-9 + -16z)] = 9 + (8z + 0)

Reorder the terms:
-1[-9 + 7z + -16z] = 9 + (8z + 0)

0 + 9z = 9 + -9 + (8z)
9z = 9 + -9 + (8z)

Combine like terms: 9 + -9 = 0
9z = 0 + (8z)
9z = (8z)

Solving
9z = (8z)

Solving for variable 'z'.

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