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


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

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

Remove parenthesis around (x + 10y)
x + 10y + -1(10x + y) = (10x + y) + (10y + x)
x + 10y + (10x * -1 + y * -1) = (10x + y) + (10y + x)
x + 10y + (-10x + -1y) = (10x + y) + (10y + x)

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

Combine like terms: x + -10x = -9x
-9x + 10y + -1y = (10x + y) + (10y + x)

Combine like terms: 10y + -1y = 9y
-9x + 9y = (10x + y) + (10y + x)

Remove parenthesis around (10x + y)
-9x + 9y = 10x + y + (10y + x)

Reorder the terms:
-9x + 9y = 10x + y + (x + 10y)

Remove parenthesis around (x + 10y)
-9x + 9y = 10x + y + x + 10y

Reorder the terms:
-9x + 9y = 10x + x + y + 10y

Combine like terms: 10x + x = 11x
-9x + 9y = 11x + y + 10y

Combine like terms: y + 10y = 11y
-9x + 9y = 11x + 11y

Solving
-9x + 9y = 11x + 11y

Solving for variable 'x'.

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

Add '-11x' to each side of the equation.
-9x + -11x + 9y = 11x + -11x + 11y

Combine like terms: -9x + -11x = -20x
-20x + 9y = 11x + -11x + 11y

Combine like terms: 11x + -11x = 0
-20x + 9y = 0 + 11y
-20x + 9y = 11y

Add '-9y' to each side of the equation.
-20x + 9y + -9y = 11y + -9y

Combine like terms: 9y + -9y = 0
-20x + 0 = 11y + -9y
-20x = 11y + -9y

Combine like terms: 11y + -9y = 2y
-20x = 2y

Divide each side by '-20'.
x = -0.1y

Simplifying
x = -0.1y
