\left(y+2\right)\times 5-\left(2y-2\right)=\left(y-2\right)\times 6
Variable y 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(y-2\right)\left(y+2\right), the least common multiple of y-2,y^{2}-4,y+2.
5y+10-\left(2y-2\right)=\left(y-2\right)\times 6
Use the distributive property to multiply y+2 by 5.
5y+10-2y+2=\left(y-2\right)\times 6
To find the opposite of 2y-2, find the opposite of each term.
3y+10+2=\left(y-2\right)\times 6
Combine 5y and -2y to get 3y.
3y+12=\left(y-2\right)\times 6
Add 10 and 2 to get 12.
3y+12=6y-12
Use the distributive property to multiply y-2 by 6.
3y+12-6y=-12
Subtract 6y from both sides.
-3y+12=-12
Combine 3y and -6y to get -3y.
-3y=-12-12
Subtract 12 from both sides.
-3y=-24
Subtract 12 from -12 to get -24.
y=\frac{-24}{-3}
Divide both sides by -3.
y=8
Divide -24 by -3 to get 8.
