Solution for 5(6z-1)-5(z+3)=9(z+1) equation:


Simplifying
5(6z + -1) + -5(z + 3) = 9(z + 1)

Reorder the terms:
5(-1 + 6z) + -5(z + 3) = 9(z + 1)
(-1 * 5 + 6z * 5) + -5(z + 3) = 9(z + 1)
(-5 + 30z) + -5(z + 3) = 9(z + 1)

Reorder the terms:
-5 + 30z + -5(3 + z) = 9(z + 1)
-5 + 30z + (3 * -5 + z * -5) = 9(z + 1)
-5 + 30z + (-15 + -5z) = 9(z + 1)

Reorder the terms:
-5 + -15 + 30z + -5z = 9(z + 1)

Combine like terms: -5 + -15 = -20
-20 + 30z + -5z = 9(z + 1)

Combine like terms: 30z + -5z = 25z
-20 + 25z = 9(z + 1)

Reorder the terms:
-20 + 25z = 9(1 + z)
-20 + 25z = (1 * 9 + z * 9)
-20 + 25z = (9 + 9z)

Solving
-20 + 25z = 9 + 9z

Solving for variable 'z'.

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