If you mean y/2 + y (without parentheses), y/2 is the same as (1/2)y, and y is the same as 1y. You can use the distributive property to combine this; in this case, the result is (3/2)y.
If you mean: (y-2)(y+2) then it is y^2 -4 which is the difference of two squares
2
y = 15 so that 13= 15 - 2 y-2 = 13 y-2 +2 = 13 +2 y = 15
X - Y = 2 When X = 3 you have 3 - Y = 2 Moving Y to RHS: 3 = Y + 2 Moving 2 to LHS: 1 = Y
