Solution for 4(3z-1)-4(z+7)=5(z+1) equation:


Simplifying
4(3z + -1) + -4(z + 7) = 5(z + 1)

Reorder the terms:
4(-1 + 3z) + -4(z + 7) = 5(z + 1)
(-1 * 4 + 3z * 4) + -4(z + 7) = 5(z + 1)
(-4 + 12z) + -4(z + 7) = 5(z + 1)

Reorder the terms:
-4 + 12z + -4(7 + z) = 5(z + 1)
-4 + 12z + (7 * -4 + z * -4) = 5(z + 1)
-4 + 12z + (-28 + -4z) = 5(z + 1)

Reorder the terms:
-4 + -28 + 12z + -4z = 5(z + 1)

Combine like terms: -4 + -28 = -32
-32 + 12z + -4z = 5(z + 1)

Combine like terms: 12z + -4z = 8z
-32 + 8z = 5(z + 1)
