Solution for 3(6z-1)-2(z+6)=9(z+1) equation:


Simplifying
3(6z + -1) + -2(z + 6) = 9(z + 1)

Reorder the terms:
3(-1 + 6z) + -2(z + 6) = 9(z + 1)
(-1 * 3 + 6z * 3) + -2(z + 6) = 9(z + 1)
(-3 + 18z) + -2(z + 6) = 9(z + 1)

Reorder the terms:
-3 + 18z + -2(6 + z) = 9(z + 1)
-3 + 18z + (6 * -2 + z * -2) = 9(z + 1)
-3 + 18z + (-12 + -2z) = 9(z + 1)

Reorder the terms:
-3 + -12 + 18z + -2z = 9(z + 1)

Combine like terms: -3 + -12 = -15
-15 + 18z + -2z = 9(z + 1)

Combine like terms: 18z + -2z = 16z
-15 + 16z = 9(z + 1)

Reorder the terms:
-15 + 16z = 9(1 + z)
-15 + 16z = (1 * 9 + z * 9)
-15 + 16z = (9 + 9z)

Solving
-15 + 16z = 9 + 9z

Solving for variable 'z'.

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