x=0.56*(x+(x+9))

Solution for x=0.56*(x+(x+9)) equation:

Simplifying
x = 0.56(x + (x + 9))

Reorder the terms:
x = 0.56(x + (9 + x))

Remove parenthesis around (9 + x)
x = 0.56(x + 9 + x)

Reorder the terms:
x = 0.56(9 + x + x)

Combine like terms: x + x = 2x
x = 0.56(9 + 2x)
x = (9 * 0.56 + 2x * 0.56)
x = (5.04 + 1.12x)

Solving
x = 5.04 + 1.12x

Solving for variable 'x'.

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

Add '-1.12x' to each side of the equation.
x + -1.12x = 5.04 + 1.12x + -1.12x

Combine like terms: x + -1.12x = -0.12x
-0.12x = 5.04 + 1.12x + -1.12x

Combine like terms: 1.12x + -1.12x = 0.00
-0.12x = 5.04 + 0.00
-0.12x = 5.04

Divide each side by '-0.12'.
x = -42

Simplifying
x = -42
