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

Good morning Brainiac The answer is A Let me solve it now to see if the solution will equal (-2,-1) 5x= -10 11x-9y = -13 Let's solve 5x=-10 for x X = -10/5 X= -2 Now we have the value for x now let find the value for y by substitute -2 for x in 11x-9y=-13 11x-9y= -13 (11)(-2)-9y= -13 -9y -22 = -13 -9y=-13+22 -9y = 9 Y= 9/-9 Y= -1 Answer (-2,-1) I hope that's help:
