Solution for 3(4z-1)-3(z+9)=2(z+1) equation:


Simplifying
3(4z + -1) + -3(z + 9) = 2(z + 1)

Reorder the terms:
3(-1 + 4z) + -3(z + 9) = 2(z + 1)
(-1 * 3 + 4z * 3) + -3(z + 9) = 2(z + 1)
(-3 + 12z) + -3(z + 9) = 2(z + 1)

Reorder the terms:
-3 + 12z + -3(9 + z) = 2(z + 1)
-3 + 12z + (9 * -3 + z * -3) = 2(z + 1)
-3 + 12z + (-27 + -3z) = 2(z + 1)

Reorder the terms:
-3 + -27 + 12z + -3z = 2(z + 1)

Combine like terms: -3 + -27 = -30
-30 + 12z + -3z = 2(z + 1)

Combine like terms: 12z + -3z = 9z
-30 + 9z = 2(z + 1)

Reorder the terms:
-30 + 9z = 2(1 + z)
-30 + 9z = (1 * 2 + z * 2)
-30 + 9z = (2 + 2z)

Solving
-30 + 9z = 2 + 2z

Solving for variable 'z'.

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