Solution for 5(4z-1)-5(z+9)=9(z+1) equation:


Simplifying
5(4z + -1) + -5(z + 9) = 9(z + 1)

Reorder the terms:
5(-1 + 4z) + -5(z + 9) = 9(z + 1)
(-1 * 5 + 4z * 5) + -5(z + 9) = 9(z + 1)
(-5 + 20z) + -5(z + 9) = 9(z + 1)

Reorder the terms:
-5 + 20z + -5(9 + z) = 9(z + 1)
-5 + 20z + (9 * -5 + z * -5) = 9(z + 1)
-5 + 20z + (-45 + -5z) = 9(z + 1)

Reorder the terms:
-5 + -45 + 20z + -5z = 9(z + 1)

Combine like terms: -5 + -45 = -50
-50 + 20z + -5z = 9(z + 1)

Combine like terms: 20z + -5z = 15z
-50 + 15z = 9(z + 1)

Reorder the terms:
-50 + 15z = 9(1 + z)
-50 + 15z = (1 * 9 + z * 9)
-50 + 15z = (9 + 9z)

Solving
-50 + 15z = 9 + 9z

Solving for variable 'z'.

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