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


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

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

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

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

Combine like terms: -2 + -18 = -20
-20 + 8z + -2z = 8(z + 1)

Combine like terms: 8z + -2z = 6z
-20 + 6z = 8(z + 1)

Reorder the terms:
-20 + 6z = 8(1 + z)
-20 + 6z = (1 * 8 + z * 8)
-20 + 6z = (8 + 8z)

Solving
-20 + 6z = 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.
-20 + 6z + -8z = 8 + 8z + -8z

Combine like terms: 6z + -8z = -2z
-20 + -2z = 8 + 8z + -8z

Combine like terms: 8z + -8z = 0
-20 + -2z = 8 + 0
-20 + -2z = 8

Add '20' to each side of the equation.
-20 + 20 + -2z = 8 + 20

Combine like terms: -20 + 20 = 0
0 + -2z = 8 + 20
-2z = 8 + 20

Combine like terms: 8 + 20 = 28
-2z = 28

Divide each side by '-2'.
z = -14

Simplifying
z = -14
