Question

What is the solution (q, r) to this system of linear equations?

12q + 3r = 15

–4q – 4r = –44

(–18, 29)
(–2, 13)
(8, –1)
(15, –44)

Answer 1

(-2,13)

Explanation:

i took the test and can confirm its 100% on edge

Answer 2

Explanation:

12q + 3r = 15

-12q - 12r = -132

-9r = -117

r = 13

12q + 3(13) = 15

12q + 39 = 15

12q = -24

q = -2

(-2, 13)

b is the answer
