Answer:
x+y=12
Step-by-step explanation:
First, substitute 3y for the spots with x:
2(3y) + 2y = 24
6y+ 2y = 24
8y= 24
y= 3
Then sub in 3 in the y place:
x= 3(3)
x= 9
Then plug in the x and y values in the equation:
9 + 3 =12
Good Luck!!!

The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186
From the polynomial given;
The polynomial can be factorised to yield a simpler form as follows;
This is so because, xy is a common factor.
The value is therefore;
- (-3×2)((-3)²2 - (-3×2²) +1)
= -186
