Solution for 5(3z-1)-3(z+2)=8(z+1) equation:


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

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

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

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

Combine like terms: -5 + -6 = -11
-11 + 15z + -3z = 8(z + 1)

Combine like terms: 15z + -3z = 12z
-11 + 12z = 8(z + 1)

Reorder the terms:
-11 + 12z = 8(1 + z)
-11 + 12z = (1 * 8 + z * 8)
-11 + 12z = (8 + 8z)

Solving
-11 + 12z = 8 + 8z

Solving for variable 'z'.

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