(x-1)(X-1)=16

Solution for (x-1)(X-1)=16 equation:

Simplifying
(x + -1)(X + -1) = 16

Reorder the terms:
(-1 + x)(X + -1) = 16

Reorder the terms:
(-1 + x)(-1 + X) = 16

Multiply (-1 + x) * (-1 + X)
(-1(-1 + X) + x(-1 + X)) = 16
((-1 * -1 + X * -1) + x(-1 + X)) = 16
((1 + -1X) + x(-1 + X)) = 16
(1 + -1X + (-1 * x + X * x)) = 16
(1 + -1X + (-1x + xX)) = 16
(1 + -1X + -1x + xX) = 16

Solving
1 + -1X + -1x + xX = 16

Solving for variable 'X'.

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

Add '-1' to each side of the equation.
1 + -1X + -1x + -1 + xX = 16 + -1

Reorder the terms:
1 + -1 + -1X + -1x + xX = 16 + -1

Combine like terms: 1 + -1 = 0
0 + -1X + -1x + xX = 16 + -1
-1X + -1x + xX = 16 + -1

Combine like terms: 16 + -1 = 15
-1X + -1x + xX = 15

Add 'x' to each side of the equation.
-1X + -1x + x + xX = 15 + x

Combine like terms: -1x + x = 0
-1X + 0 + xX = 15 + x
-1X + xX = 15 + x

Reorder the terms:
-15 + -1X + -1x + xX = 15 + x + -15 + -1x

Reorder the terms:
-15 + -1X + -1x + xX = 15 + -15 + x + -1x

Combine like terms: 15 + -15 = 0
-15 + -1X + -1x + xX = 0 + x + -1x
-15 + -1X + -1x + xX = x + -1x

Combine like terms: x + -1x = 0
-15 + -1X + -1x + xX = 0
