Solution for 5(4z-1)-5(z+1)=8(z+1) equation:


Simplifying
5(4z + -1) + -5(z + 1) = 8(z + 1)

Reorder the terms:
5(-1 + 4z) + -5(z + 1) = 8(z + 1)
(-1 * 5 + 4z * 5) + -5(z + 1) = 8(z + 1)
(-5 + 20z) + -5(z + 1) = 8(z + 1)

Reorder the terms:
-5 + 20z + -5(1 + z) = 8(z + 1)
-5 + 20z + (1 * -5 + z * -5) = 8(z + 1)
-5 + 20z + (-5 + -5z) = 8(z + 1)

Reorder the terms:
-5 + -5 + 20z + -5z = 8(z + 1)

Combine like terms: -5 + -5 = -10
-10 + 20z + -5z = 8(z + 1)

Combine like terms: 20z + -5z = 15z
-10 + 15z = 8(z + 1)

Reorder the terms:
-10 + 15z = 8(1 + z)
-10 + 15z = (1 * 8 + z * 8)
-10 + 15z = (8 + 8z)

Solving
-10 + 15z = 8 + 8z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.
