x=\left(x+2\right)\times 2
Variable x cannot be equal to any of the values -2,0 since division by zero is not defined. Multiply both sides of the equation by x\left(x+2\right), the least common multiple of x+2,x.
x=2x+4
Use the distributive property to multiply x+2 by 2.
x-2x=4
Subtract 2x from both sides.
-x=4
Combine x and -2x to get -x.
x=-4
Multiply both sides by -1.
