Answer:
The solution is (3,-6).
Step-by-step explanation:
Solving the system of linear equation using the elimination method.
Let,
-20x = -96 -6y ----equation 1
-16x = -84 -6y ----equation 2
Now subtracting both the equation 2 from equation 1
-20x = -96 -6y
+16x = +84 +6y
-4x = -12
dividing -4 on both sides
-4x/(-4) = -12/-4
x = 3
Now put the value of x in equation 1
-20x = -96 -6y
-20(3) = -96 -6y
-60 +96 = -96 +96 -6y
36 = -6y
36/(-6) = -6y/(-6)
-6 = y
Soution (3,-6)
