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


Simplifying
(4 + -1x)(3x + -1) = 4 + -1x

Reorder the terms:
(4 + -1x)(-1 + 3x) = 4 + -1x

Multiply (4 + -1x) * (-1 + 3x)
(4(-1 + 3x) + -1x * (-1 + 3x)) = 4 + -1x
((-1 * 4 + 3x * 4) + -1x * (-1 + 3x)) = 4 + -1x
((-4 + 12x) + -1x * (-1 + 3x)) = 4 + -1x
(-4 + 12x + (-1 * -1x + 3x * -1x)) = 4 + -1x
(-4 + 12x + (1x + -3x2)) = 4 + -1x

Combine like terms: 12x + 1x = 13x
(-4 + 13x + -3x2) = 4 + -1x

Solving
-4 + 13x + -3x2 = 4 + -1x

Solving for variable 'x'.

Reorder the terms:
-4 + -4 + 13x + x + -3x2 = 4 + -1x + -4 + x

Combine like terms: -4 + -4 = -8
-8 + 13x + x + -3x2 = 4 + -1x + -4 + x

Combine like terms: 13x + x = 14x
-8 + 14x + -3x2 = 4 + -1x + -4 + x

Reorder the terms:
-8 + 14x + -3x2 = 4 + -4 + -1x + x

Combine like terms: 4 + -4 = 0
-8 + 14x + -3x2 = 0 + -1x + x
-8 + 14x + -3x2 = -1x + x
