\left(x-2\right)\times 2+\left(x+2\right)\times 5=6
Variable x cannot be equal to any of the values -2,2 since division by zero is not defined. Multiply both sides of the equation by \left(x-2\right)\left(x+2\right), the least common multiple of x+2,x-2,x^{2}-4.
2x-4+\left(x+2\right)\times 5=6
Use the distributive property to multiply x-2 by 2.
2x-4+5x+10=6
Use the distributive property to multiply x+2 by 5.
7x-4+10=6
Combine 2x and 5x to get 7x.
7x+6=6
Add -4 and 10 to get 6.
7x=6-6
Subtract 6 from both sides.
7x=0
Subtract 6 from 6 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 7 is not equal to 0, x must be equal to 0.
