Simplifying
6(2z + -1) + -5(z + 2) = 4(z + 1)

Reorder the terms:
6(-1 + 2z) + -5(z + 2) = 4(z + 1)
(-1 * 6 + 2z * 6) + -5(z + 2) = 4(z + 1)
(-6 + 12z) + -5(z + 2) = 4(z + 1)

Reorder the terms:
-6 + 12z + -5(2 + z) = 4(z + 1)
-6 + 12z + (2 * -5 + z * -5) = 4(z + 1)
-6 + 12z + (-10 + -5z) = 4(z + 1)

Reorder the terms:
-6 + -10 + 12z + -5z = 4(z + 1)

Combine like terms: -6 + -10 = -16
-16 + 12z + -5z = 4(z + 1)

Combine like terms: 12z + -5z = 7z
-16 + 7z = 4(z + 1)
