r(x+2)-x=0

Solution for r(x+2)-x=0 equation:

Simplifying
r(x + 2) + -1x = 0

Reorder the terms:
r(2 + x) + -1x = 0
(2 * r + x * r) + -1x = 0
(2r + rx) + -1x = 0

Solving
2r + rx + -1x = 0

Solving for variable 'r'.

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

Add 'x' to each side of the equation.
2r + rx + -1x + x = 0 + x

Combine like terms: -1x + x = 0
2r + rx + 0 = 0 + x
2r + rx = 0 + x
Remove the zero:
2r + rx = x

Combine like terms: x + -1x = 0
2r + rx + -1x = 0
