Solution for 3(4z-1)-2(z+8)=7(z+1) equation:


Simplifying
3(4z + -1) + -2(z + 8) = 7(z + 1)

Reorder the terms:
3(-1 + 4z) + -2(z + 8) = 7(z + 1)
(-1 * 3 + 4z * 3) + -2(z + 8) = 7(z + 1)
(-3 + 12z) + -2(z + 8) = 7(z + 1)

Reorder the terms:
-3 + 12z + -2(8 + z) = 7(z + 1)
-3 + 12z + (8 * -2 + z * -2) = 7(z + 1)
-3 + 12z + (-16 + -2z) = 7(z + 1)

Reorder the terms:
-3 + -16 + 12z + -2z = 7(z + 1)

Combine like terms: -3 + -16 = -19
-19 + 12z + -2z = 7(z + 1)

Combine like terms: 12z + -2z = 10z
-19 + 10z = 7(z + 1)

Reorder the terms:
-19 + 10z = 7(1 + z)
-19 + 10z = (1 * 7 + z * 7)
-19 + 10z = (7 + 7z)

Solving
-19 + 10z = 7 + 7z

Solving for variable 'z'.

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