x=.5(x-8+2x-4)

Solution for x=.5(x-8+2x-4) equation:

Simplifying
x = 0.5(x + -8 + 2x + -4)

Reorder the terms:
x = 0.5(-8 + -4 + x + 2x)

Combine like terms: -8 + -4 = -12
x = 0.5(-12 + x + 2x)

Combine like terms: x + 2x = 3x
x = 0.5(-12 + 3x)
x = (-12 * 0.5 + 3x * 0.5)
x = (-6 + 1.5x)

Solving
x = -6 + 1.5x

Solving for variable 'x'.

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

Add '-1.5x' to each side of the equation.
x + -1.5x = -6 + 1.5x + -1.5x

Combine like terms: x + -1.5x = -0.5x
-0.5x = -6 + 1.5x + -1.5x

Combine like terms: 1.5x + -1.5x = 0.0
-0.5x = -6 + 0.0
-0.5x = -6

Divide each side by '-0.5'.
x = 12

Simplifying
x = 12
