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


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

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

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

Reorder the terms:
-5 + -3 + 15z + -3z = 3(z + 1)

Combine like terms: -5 + -3 = -8
-8 + 15z + -3z = 3(z + 1)

Combine like terms: 15z + -3z = 12z
-8 + 12z = 3(z + 1)
