(x+1)(y-1)=10

Solution for (x+1)(y-1)=10 equation:

Simplifying
(x + 1)(y + -1) = 10

Reorder the terms:
(1 + x)(y + -1) = 10

Reorder the terms:
(1 + x)(-1 + y) = 10

Multiply (1 + x) * (-1 + y)
(1(-1 + y) + x(-1 + y)) = 10
((-1 * 1 + y * 1) + x(-1 + y)) = 10
((-1 + 1y) + x(-1 + y)) = 10
(-1 + 1y + (-1 * x + y * x)) = 10
(-1 + 1y + (-1x + xy)) = 10

Reorder the terms:
(-1 + -1x + xy + 1y) = 10
(-1 + -1x + xy + 1y) = 10

Solving
-1 + -1x + xy + 1y = 10

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 + xy + 1 + 1y = 10 + 1

Reorder the terms:
-1 + 1 + -1x + xy + 1y = 10 + 1

Combine like terms: -1 + 1 = 0
0 + -1x + xy + 1y = 10 + 1
-1x + xy + 1y = 10 + 1

Combine like terms: 10 + 1 = 11
-1x + xy + 1y = 11

Add '-1y' to each side of the equation.
-1x + xy + 1y + -1y = 11 + -1y

Combine like terms: 1y + -1y = 0
-1x + xy + 0 = 11 + -1y
-1x + xy = 11 + -1y

Reorder the terms:
-11 + -1x + xy + y = 11 + -1y + -11 + y

Reorder the terms:
-11 + -1x + xy + y = 11 + -11 + -1y + y

Combine like terms: 11 + -11 = 0
-11 + -1x + xy + y = 0 + -1y + y
-11 + -1x + xy + y = -1y + y

Combine like terms: -1y + y = 0
-11 + -1x + xy + y = 0
