Solution for 4(3z-1)-4(z+8)=3(z+1) equation:


Simplifying
4(3z + -1) + -4(z + 8) = 3(z + 1)

Reorder the terms:
4(-1 + 3z) + -4(z + 8) = 3(z + 1)
(-1 * 4 + 3z * 4) + -4(z + 8) = 3(z + 1)
(-4 + 12z) + -4(z + 8) = 3(z + 1)

Reorder the terms:
-4 + 12z + -4(8 + z) = 3(z + 1)
-4 + 12z + (8 * -4 + z * -4) = 3(z + 1)
-4 + 12z + (-32 + -4z) = 3(z + 1)

Reorder the terms:
-4 + -32 + 12z + -4z = 3(z + 1)

Combine like terms: -4 + -32 = -36
-36 + 12z + -4z = 3(z + 1)

Combine like terms: 12z + -4z = 8z
-36 + 8z = 3(z + 1)

Reorder the terms:
-36 + 8z = 3(1 + z)
-36 + 8z = (1 * 3 + z * 3)
-36 + 8z = (3 + 3z)

Solving
-36 + 8z = 3 + 3z

Solving for variable 'z'.

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