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
