here is the set of answers

Answer 4

ok

Answer 5

(2, -1)

(4, -1)

(5, -2)

Answer 6

and A was (-4, 1)

Answer 7

x + 3y = -1 ----> x = -3y - 1

now sub -3y - 1 in for x in the other equation
2x + 2y = 6
2(-3y - 1) + 2y = 6
-6y - 2 + 2y = 6
-6y + 2y = 6 + 2
-4y = 8
y = -2

now sub -2 in for y in either equation to find x
x + 3y = -1
x + 3(-2) = -1
x - 6 = -1
x = -1 + 6
x = 5

solution is : (5,-2)
