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)? (a) 5x = −10 11x − 9y = −13 (b) 2x 9y = −1 11x − 9y = −13 (c) −6x 9y = −1 11x − 9y = −13 (d) −6x 3y = −1 5x = −10
