Question

Is (1,7) a solution to this system of equations?

8x + y = 15
4x + 2y = 18
yes
no

Answer 1

Yes

Explanation:

Plug in the values for x and y: (x, y) = (1, 7)

8(1) + 7 = 15

8 + 7 = 15

15 = 15

Correct

4(1) + 2(7) = 18

4 + 14 = 18

18 = 18

Correct

Answer 2

Answer: Yes

Step-by-step explanation: If you plug in the x and y into the equations you will find them to be true.
