Solution for 3(6z-1)-2(z+3)=12(z+1) equation:


Simplifying
3(6z + -1) + -2(z + 3) = 12(z + 1)

Reorder the terms:
3(-1 + 6z) + -2(z + 3) = 12(z + 1)
(-1 * 3 + 6z * 3) + -2(z + 3) = 12(z + 1)
(-3 + 18z) + -2(z + 3) = 12(z + 1)

Reorder the terms:
-3 + 18z + -2(3 + z) = 12(z + 1)
-3 + 18z + (3 * -2 + z * -2) = 12(z + 1)
-3 + 18z + (-6 + -2z) = 12(z + 1)

Reorder the terms:
-3 + -6 + 18z + -2z = 12(z + 1)

Combine like terms: -3 + -6 = -9
-9 + 18z + -2z = 12(z + 1)

Combine like terms: 18z + -2z = 16z
-9 + 16z = 12(z + 1)

Reorder the terms:
-9 + 16z = 12(1 + z)
-9 + 16z = (1 * 12 + z * 12)
-9 + 16z = (12 + 12z)

Solving
-9 + 16z = 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.
-9 + 16z + -12z = 12 + 12z + -12z

Combine like terms: 16z + -12z = 4z
-9 + 4z = 12 + 12z + -12z

Combine like terms: 12z + -12z = 0
-9 + 4z = 12 + 0
-9 + 4z = 12

Add '9' to each side of the equation.
-9 + 9 + 4z = 12 + 9

Combine like terms: -9 + 9 = 0
0 + 4z = 12 + 9
4z = 12 + 9
