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


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

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

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

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

Combine like terms: -4 + -20 = -24
-24 + 20z + -5z = 5(z + 1)

Combine like terms: 20z + -5z = 15z
-24 + 15z = 5(z + 1)

Reorder the terms:
-24 + 15z = 5(1 + z)
-24 + 15z = (1 * 5 + z * 5)
-24 + 15z = (5 + 5z)

Solving
-24 + 15z = 5 + 5z

Solving for variable 'z'.
