Solution for 5(3z-1)-5(z+2)=6(z+1) equation:


Simplifying
5(3z + -1) + -5(z + 2) = 6(z + 1)

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

Reorder the terms:
-5 + 15z + -5(2 + z) = 6(z + 1)
-5 + 15z + (2 * -5 + z * -5) = 6(z + 1)
-5 + 15z + (-10 + -5z) = 6(z + 1)

Reorder the terms:
-5 + -10 + 15z + -5z = 6(z + 1)

Combine like terms: -5 + -10 = -15
-15 + 15z + -5z = 6(z + 1)

Combine like terms: 15z + -5z = 10z
-15 + 10z = 6(z + 1)

Reorder the terms:
-15 + 10z = 6(1 + z)
-15 + 10z = (1 * 6 + z * 6)
-15 + 10z = (6 + 6z)

Solving
-15 + 10z = 6 + 6z

Solving for variable 'z'.

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