((1.0-x)+(2.0-3x)+2x)=2.2

Solution for ((1.0-x)+(2.0-3x)+2x)=2.2 equation:

Simplifying
((1.0 + -1x) + (2.0 + -3x) + 2x) = 2.2

Remove parenthesis around (1.0 + -1x)
(1.0 + -1x + (2.0 + -3x) + 2x) = 2.2

Remove parenthesis around (2.0 + -3x)
(1.0 + -1x + 2.0 + -3x + 2x) = 2.2

Reorder the terms:
(1.0 + 2.0 + -1x + -3x + 2x) = 2.2

Combine like terms: 1.0 + 2.0 = 3
(3 + -1x + -3x + 2x) = 2.2

Combine like terms: -1x + -3x = -4x
(3 + -4x + 2x) = 2.2

Combine like terms: -4x + 2x = -2x
(3 + -2x) = 2.2

Remove parenthesis around (3 + -2x)
3 + -2x = 2.2

Solving
3 + -2x = 2.2

Solving for variable 'x'.

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

Add '-3' to each side of the equation.
3 + -3 + -2x = 2.2 + -3

Combine like terms: 3 + -3 = 0
0 + -2x = 2.2 + -3
-2x = 2.2 + -3

Combine like terms: 2.2 + -3 = -0.8
-2x = -0.8

Divide each side by '-2'.
x = 0.4

Simplifying
x = 0.4
