Question

Solve this system of linear equations. Separate

the x- and y-values with a comma.
13x = -21 - 6y
-8x = 36 + +6y

Answer 1

Is very good guestion

keep it up

Answer 2

x=3,y=-10

Explanation:

First, we add 21 to both sides of the first equation

13x=-21-6y

+21 +21

13x+21=-6y Now divide by -1 to make it positive

/-1 /-1 /-1

-13x-21=6y

Now we have to subtract 36 on both sides of the second equation

-8x=36+6y

-36 -36

-8x-36=6y

Since both equations equal 6y we can solve the equation by making them "equal" each other

-13x-21=-8x-36 Add 36 to both sides

+36 +36

-13x+15=-8x Add 13x to both sides

+13x +13x

15=5x Divide by 5

/5 /5

x=3

Now use the x value to solve

13(3)=-21-6y

39=-21-6y Add 21 to both sides

+21 +21

60=-6y

/-6 /-6

y=-10

Hope this helped!
