Simplifying
3(2z + -1) + -2(x + 9) = 2(z + 1)

Reorder the terms:
3(-1 + 2z) + -2(x + 9) = 2(z + 1)
(-1 * 3 + 2z * 3) + -2(x + 9) = 2(z + 1)
(-3 + 6z) + -2(x + 9) = 2(z + 1)

Reorder the terms:
-3 + 6z + -2(9 + x) = 2(z + 1)
-3 + 6z + (9 * -2 + x * -2) = 2(z + 1)
-3 + 6z + (-18 + -2x) = 2(z + 1)

Reorder the terms:
-3 + -18 + -2x + 6z = 2(z + 1)

Combine like terms: -3 + -18 = -21
-21 + -2x + 6z = 2(z + 1)
