The solution to the system of equation below is (−2, −1).

2x − 3y = −1
11x − 9y = −13

when the first equation is multiplied by −3, the sum of the two equations is equivalent to 5x = −10.

which system of equations will also have a solution of (−2, −1)?

5x = −10
11x − 9y = −13

2x + 9y = −1
11x − 9y = −13

−6x + 9y = −1
11x − 9y = −13

−6x + 3y = −1
5x = −10
