Simplifying
3(5z + -1) + -2(z + 8) = 6(z + 1)

Reorder the terms:
3(-1 + 5z) + -2(z + 8) = 6(z + 1)
(-1 * 3 + 5z * 3) + -2(z + 8) = 6(z + 1)
(-3 + 15z) + -2(z + 8) = 6(z + 1)

Reorder the terms:
-3 + 15z + -2(8 + z) = 6(z + 1)
-3 + 15z + (8 * -2 + z * -2) = 6(z + 1)
-3 + 15z + (-16 + -2z) = 6(z + 1)
