Question

A system of equations is shown below:

y = 8x − 2
y = 9x − 7

What is the solution to the system of equations?

(−5, 38)
(−5, −38)
(5, 38)
(5, −38)

Answer 1

Answer would be C (5, 38)

Answer 2

y = 8x - 2
y = 9x - 7

8x - 2 = 9x - 7
- 8x - 8x
-2 = x - 7
+ 7 + 7
5 = x

y = 8x -2
y = 8(5) - 2
y = 40 - 2
y = 38
(x, y) = (5, 38)

The answer is C.
