Solution for 2(6z-1)-3(z+8)=7(z+1) equation:


Simplifying
2(6z + -1) + -3(z + 8) = 7(z + 1)

Reorder the terms:
2(-1 + 6z) + -3(z + 8) = 7(z + 1)
(-1 * 2 + 6z * 2) + -3(z + 8) = 7(z + 1)
(-2 + 12z) + -3(z + 8) = 7(z + 1)

Reorder the terms:
-2 + 12z + -3(8 + z) = 7(z + 1)
-2 + 12z + (8 * -3 + z * -3) = 7(z + 1)
-2 + 12z + (-24 + -3z) = 7(z + 1)

Reorder the terms:
-2 + -24 + 12z + -3z = 7(z + 1)

Combine like terms: -2 + -24 = -26
-26 + 12z + -3z = 7(z + 1)

Combine like terms: 12z + -3z = 9z
-26 + 9z = 7(z + 1)

Reorder the terms:
-26 + 9z = 7(1 + z)
-26 + 9z = (1 * 7 + z * 7)
-26 + 9z = (7 + 7z)

Solving
-26 + 9z = 7 + 7z

Solving for variable 'z'.

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

Add '-7z' to each side of the equation.
-26 + 9z + -7z = 7 + 7z + -7z

Combine like terms: 9z + -7z = 2z
-26 + 2z = 7 + 7z + -7z

Combine like terms: 7z + -7z = 0
-26 + 2z = 7 + 0
-26 + 2z = 7
