1) Which ordered pair is the solution to the system of equations?

{x+y=-13x-y=21

(5.5, - 6.5)

(10, - 11)

(5, - 6)

(7, - 8)

The ordered pair that is the solution to the system of equations cane be solve by adding the two term

(x + y=-13) + (x-y=21) = (2x = 8)

X = 4

Substitute x to the first equation

4 + y = - 13

Y = - 17
