Question

What is the solution to the system of equations?
10x+3y=43
-9x-y=-20
(11, 1)
(1, 11)
(–1, 11)
(11, –1)

Answer 1

The answer is (1,11). You can solve for x first and plugged it in to find y.

Answer 2

Answer:

(1, 11)

Step-by-step explanation:

If you plug  both of these values in for the x and y in both equations you will get a true statement.

10(1) + 3(11) = 43

10 + 33 = 43

-9(1) - (11) = -20

-9 - 11 = -20
