-3x-y=11 *2 both sides
-9x-2y=34
--> -6x-2y=22
-9x-2y=34 subtract second equ from the first
--> 3x=-12
--> x=-4
Substitute -4 in the first equ
--> -6*-4-2y=22
--> 24-2y=22
--> -2y=22-24
--> y=-2/-2=1
Write the system of equations as an augmented matrix. Then solve for x and y.
-3x-y=11
-9x-2y=34
Solution =
