Solution for 4x-2(1-x)=2(3x-2r) equation:


Simplifying
4x + -2(1 + -1x) = 2(3x + -2r)
4x + (1 * -2 + -1x * -2) = 2(3x + -2r)
4x + (-2 + 2x) = 2(3x + -2r)

Reorder the terms:
-2 + 4x + 2x = 2(3x + -2r)

Combine like terms: 4x + 2x = 6x
-2 + 6x = 2(3x + -2r)

Reorder the terms:
-2 + 6x = 2(-2r + 3x)
-2 + 6x = (-2r * 2 + 3x * 2)
-2 + 6x = (-4r + 6x)

Add '-6x' to each side of the equation.
-2 + 6x + -6x = -4r + 6x + -6x

Combine like terms: 6x + -6x = 0
-2 + 0 = -4r + 6x + -6x
-2 = -4r + 6x + -6x

Combine like terms: 6x + -6x = 0
-2 = -4r + 0
-2 = -4r

Solving
-2 = -4r

Solving for variable 'r'.

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

Add '4r' to each side of the equation.
-2 + 4r = -4r + 4r

Combine like terms: -4r + 4r = 0
-2 + 4r = 0

Add '2' to each side of the equation.
-2 + 2 + 4r = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 4r = 0 + 2
4r = 0 + 2

Combine like terms: 0 + 2 = 2
4r = 2

Divide each side by '4'.
r = 0.5

Simplifying
r = 0.5
