Solution for 4(5z-1)-5(z+8)=7(z+1) equation:


Simplifying
4(5z + -1) + -5(z + 8) = 7(z + 1)

Reorder the terms:
4(-1 + 5z) + -5(z + 8) = 7(z + 1)
(-1 * 4 + 5z * 4) + -5(z + 8) = 7(z + 1)
(-4 + 20z) + -5(z + 8) = 7(z + 1)

Reorder the terms:
-4 + 20z + -5(8 + z) = 7(z + 1)
-4 + 20z + (8 * -5 + z * -5) = 7(z + 1)
-4 + 20z + (-40 + -5z) = 7(z + 1)

Reorder the terms:
-4 + -40 + 20z + -5z = 7(z + 1)

Combine like terms: -4 + -40 = -44
-44 + 20z + -5z = 7(z + 1)

Combine like terms: 20z + -5z = 15z
-44 + 15z = 7(z + 1)

Reorder the terms:
-44 + 15z = 7(1 + z)
-44 + 15z = (1 * 7 + z * 7)
-44 + 15z = (7 + 7z)

Solving
-44 + 15z = 7 + 7z

Solving for variable 'z'.

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