Solution for 3(6z-1)-4(z+3)=12(z+1) equation:


Simplifying
3(6z + -1) + -4(z + 3) = 12(z + 1)

Reorder the terms:
3(-1 + 6z) + -4(z + 3) = 12(z + 1)
(-1 * 3 + 6z * 3) + -4(z + 3) = 12(z + 1)
(-3 + 18z) + -4(z + 3) = 12(z + 1)

Reorder the terms:
-3 + 18z + -4(3 + z) = 12(z + 1)
-3 + 18z + (3 * -4 + z * -4) = 12(z + 1)
-3 + 18z + (-12 + -4z) = 12(z + 1)

Reorder the terms:
-3 + -12 + 18z + -4z = 12(z + 1)

Combine like terms: -3 + -12 = -15
-15 + 18z + -4z = 12(z + 1)

Combine like terms: 18z + -4z = 14z
-15 + 14z = 12(z + 1)

Reorder the terms:
-15 + 14z = 12(1 + z)
-15 + 14z = (1 * 12 + z * 12)
-15 + 14z = (12 + 12z)

Solving
-15 + 14z = 12 + 12z

Solving for variable 'z'.

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

Add '-12z' to each side of the equation.
