Let's see first x-y=-3. You can find x and x=-3+y
Then you replace x in x+3y=5
-3+y+3y=5
4y=8
y=2 But you have to find x too.
x=-3+2 x=-1
The answers are x=-1, y=2
Perimeter is the distance around the rectangle and the formula is 2 x length + 2 x height.
Perimeter = 2 x45 + 2x20
Perimeter = 90 + 40
Perimeter = 130 yards
The answer is -15 if you want it solved
