Question

What is the x-value in the solution to this system of linear equations?

2x+3y=3

7x-3y=24

a. (2,7)
b. (3,-21)
c. (3,-1)
d. (9,0)

Answer 1

To solve linear equations, you can add them together.

2x+3y=3

7x-3y=24

9x=27

x=3

Then you plug in your answer in to solve for y.

2(3)+3y=3

6+3y=3

3y=-3

y=-1

So your answer is C.
