Question

Solve the system of equations and chose the correct ordered pair 3y=6x-18 7y=6x+6 A(3,6) B(6,0) C(3,0) D(6,6)

Answer 1

We don't really have to solve it because we can try out the pairs and get D(6,6).

OK, let's solve it.

3y = 6x - 18

7y = 6x + 6

Subtracting,

4y = 24

y = 6

6x = 7y- 6 =7(6)-6=36

x=6

Choice D(6,6)
