Answer 4

I got (2,-5)

Answer 5

2y = 6x - 22
y = 3x - 11
2x + 3•(3x-11) = -11
11x = 22
x=2
y = 3(2)11 = -5

Answer 6

Solve the system by substitution.

y = 2x
3x + 2y = 21
A.
x = 3, y = 6
B.
x = 6, y = 3
C.
x = 3, y = –6
D.
x = –6, y = 3

Answer 7

Okay You plug the first equation into the second one which gives you 3x+2(2x)=21
3x+4x=21
7x=21
x=3
So now plug 3 into the first equation to get y
y=2(3)
y=6
(3,6)
