Answer:

x=3

y=-4

Step-by-step explanation:

-7x-2y=-13 ---(1)

x=2y+11

sub (2) into (1), -7(2y+11)-2y=-13

                          -14y-2y-77=-13

                                     -16y=64

                                          y=-4

put y=-4 into (2), x=2(-4)+11

                            x=3

btw, next time, do not use words like(failing,exam,free points,etc in ur caption or content),otherwise,the question would be deleted.

-7x -2y = 13, and then to solve it we put in (2y + 11) where it says x.

So
-7(2y +11) -2y = 13 , then distribute the -7

-14y -77 -2y = 13
-16y -77 = 13
-16y = 64
y = -4
