2x+2+\left(2x-2\right)\times 5-2x=\left(x+1\right)\times 3
Variable x cannot be equal to any of the values -1,1 since division by zero is not defined. Multiply both sides of the equation by 2\left(x-1\right)\left(x+1\right), the least common multiple of x-1,x+1,x^{2}-1,2x-2.
2x+2+10x-10-2x=\left(x+1\right)\times 3
Use the distributive property to multiply 2x-2 by 5.
12x+2-10-2x=\left(x+1\right)\times 3
Combine 2x and 10x to get 12x.
12x-8-2x=\left(x+1\right)\times 3
Subtract 10 from 2 to get -8.
10x-8=\left(x+1\right)\times 3
Combine 12x and -2x to get 10x.
10x-8=3x+3
Use the distributive property to multiply x+1 by 3.
10x-8-3x=3
Subtract 3x from both sides.
7x-8=3
Combine 10x and -3x to get 7x.
7x=3+8
Add 8 to both sides.
7x=11
Add 3 and 8 to get 11.
x=\frac{11}{7}
Divide both sides by 7.
