The answer would probably 3 because there is 1 x and y plus a 10
If the domain is 5, you just put that five where you find an x. So,
y = 5 - 5
y = 0
Domain means those are the numbers that will be set as x's in the equation
(x^2-y^2)+(2x+2y)= (x+y).(x-y) +2.(x+y) = (x+y).(x-y+2)
4x=-7 is the answer because "the number" should be the variable
