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)

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
