Question

Solve this system of linear equations. Separate the x- and the y- values with a comma.

-20x= -96-6y
-16x= -84-6y

Answer 1

3,-6

Explanation:

Answer 2

The solution is (3,-6).

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)
