Solution for (1-x)(2a-1)=2(a+2) equation:


Simplifying
(1 + -1x)(2a + -1) = 2(a + 2)

Reorder the terms:
(1 + -1x)(-1 + 2a) = 2(a + 2)

Multiply (1 + -1x) * (-1 + 2a)
(1(-1 + 2a) + -1x * (-1 + 2a)) = 2(a + 2)
((-1 * 1 + 2a * 1) + -1x * (-1 + 2a)) = 2(a + 2)
((-1 + 2a) + -1x * (-1 + 2a)) = 2(a + 2)
(-1 + 2a + (-1 * -1x + 2a * -1x)) = 2(a + 2)

Reorder the terms:
(-1 + 2a + (-2ax + 1x)) = 2(a + 2)
(-1 + 2a + (-2ax + 1x)) = 2(a + 2)
(-1 + 2a + -2ax + 1x) = 2(a + 2)

Reorder the terms:
-1 + 2a + -2ax + 1x = 2(2 + a)
-1 + 2a + -2ax + 1x = (2 * 2 + a * 2)
-1 + 2a + -2ax + 1x = (4 + 2a)

Add '-2a' to each side of the equation.
-1 + 2a + -2ax + -2a + 1x = 4 + 2a + -2a

Reorder the terms:
-1 + 2a + -2a + -2ax + 1x = 4 + 2a + -2a

Combine like terms: 2a + -2a = 0
-1 + 0 + -2ax + 1x = 4 + 2a + -2a
-1 + -2ax + 1x = 4 + 2a + -2a

Combine like terms: 2a + -2a = 0
-1 + -2ax + 1x = 4 + 0
-1 + -2ax + 1x = 4

Solving
-1 + -2ax + 1x = 4

Solving for variable 'a'.

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