Solution for 4(6z-1)-4(z+4)=7(z+1) equation:


Simplifying
4(6z + -1) + -4(z + 4) = 7(z + 1)

Reorder the terms:
4(-1 + 6z) + -4(z + 4) = 7(z + 1)
(-1 * 4 + 6z * 4) + -4(z + 4) = 7(z + 1)
(-4 + 24z) + -4(z + 4) = 7(z + 1)

Reorder the terms:
-4 + 24z + -4(4 + z) = 7(z + 1)
-4 + 24z + (4 * -4 + z * -4) = 7(z + 1)
-4 + 24z + (-16 + -4z) = 7(z + 1)

Reorder the terms:
-4 + -16 + 24z + -4z = 7(z + 1)

Combine like terms: -4 + -16 = -20
-20 + 24z + -4z = 7(z + 1)

Combine like terms: 24z + -4z = 20z
-20 + 20z = 7(z + 1)

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

Solving
-20 + 20z = 7 + 7z

Solving for variable 'z'.

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