Solution for 4(5z-1)-4(z+2)=7(z+1) equation:


Simplifying
4(5z + -1) + -4(z + 2) = 7(z + 1)

Reorder the terms:
4(-1 + 5z) + -4(z + 2) = 7(z + 1)
(-1 * 4 + 5z * 4) + -4(z + 2) = 7(z + 1)
(-4 + 20z) + -4(z + 2) = 7(z + 1)

Reorder the terms:
-4 + 20z + -4(2 + z) = 7(z + 1)
-4 + 20z + (2 * -4 + z * -4) = 7(z + 1)
-4 + 20z + (-8 + -4z) = 7(z + 1)

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

Combine like terms: -4 + -8 = -12
-12 + 20z + -4z = 7(z + 1)

Combine like terms: 20z + -4z = 16z
-12 + 16z = 7(z + 1)

Reorder the terms:
-12 + 16z = 7(1 + z)
-12 + 16z = (1 * 7 + z * 7)
-12 + 16z = (7 + 7z)

Solving
-12 + 16z = 7 + 7z

Solving for variable 'z'.

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

Add '-7z' to each side of the equation.
