Simplifying
2(6z + -1) + -3(z + 7) = 6(z + 1)

Reorder the terms:
2(-1 + 6z) + -3(z + 7) = 6(z + 1)
(-1 * 2 + 6z * 2) + -3(z + 7) = 6(z + 1)
(-2 + 12z) + -3(z + 7) = 6(z + 1)

Reorder the terms:
-2 + 12z + -3(7 + z) = 6(z + 1)
-2 + 12z + (7 * -3 + z * -3) = 6(z + 1)
-2 + 12z + (-21 + -3z) = 6(z + 1)

Reorder the terms:
-2 + -21 + 12z + -3z = 6(z + 1)

Combine like terms: -2 + -21 = -23
-23 + 12z + -3z = 6(z + 1)

Combine like terms: 12z + -3z = 9z
-23 + 9z = 6(z + 1)
