Solution for 3(4z-1)-2(z+9)=8(z+1) equation:


Simplifying
3(4z + -1) + -2(z + 9) = 8(z + 1)

Reorder the terms:
3(-1 + 4z) + -2(z + 9) = 8(z + 1)
(-1 * 3 + 4z * 3) + -2(z + 9) = 8(z + 1)
(-3 + 12z) + -2(z + 9) = 8(z + 1)

Reorder the terms:
-3 + 12z + -2(9 + z) = 8(z + 1)
-3 + 12z + (9 * -2 + z * -2) = 8(z + 1)
-3 + 12z + (-18 + -2z) = 8(z + 1)

Reorder the terms:
-3 + -18 + 12z + -2z = 8(z + 1)

Combine like terms: -3 + -18 = -21
-21 + 12z + -2z = 8(z + 1)

Combine like terms: 12z + -2z = 10z
-21 + 10z = 8(z + 1)

Reorder the terms:
-21 + 10z = 8(1 + z)
-21 + 10z = (1 * 8 + z * 8)
-21 + 10z = (8 + 8z)

Solving
-21 + 10z = 8 + 8z

Solving for variable 'z'.

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

Add '-8z' to each side of the equation.
-21 + 10z + -8z = 8 + 8z + -8z

Combine like terms: 10z + -8z = 2z
-21 + 2z = 8 + 8z + -8z

Combine like terms: 8z + -8z = 0
-21 + 2z = 8 + 0
-21 + 2z = 8
