Question

Solve the system, using substitution. Write the solution as an ordered pair.

x = 2y - 2 and 3x - y = 14

A. (6, 4)
B. (4, 6)
C. (1, 0)
D. (0, 1)
E. no solution

I put D is that correct? (:

Answer 1

i got A here.

Answer 2

Okay (: Are you sure this time? :D

Answer 3

just substitute 2y-2 for the x in equation 3x-y=14
3(2y-2)-y=14
6y-6-y=14
5y-6=14
5y=20
y=4

Answer 4

then plug in 4 in for y in the equation x = 2y - 2
x=2(4)-2
x=8-2
x=6

Answer 5

Wait... wouldnt x = 4?
