Question

Solve this system of linear equations. Separate

the x- and y-values with a comma.
6x + 20y = -62
3x - 9y = -12
Enter the correct answer
DONE

Answer 1

(-41/3 ,1)

Explanation:

Step 1. Multiply so we can eliminate x and solve for y

6x + 20y = -62

2(3x - 9y = -12)

6x + 20y = -62

- 6x - 18y = -24

--------------------------

38y = -38

y = 1

Step 2. Solve for x

6x + 20(1) = -62

6x = -82

x = -41/3

(-41/3,1)

Answer 2

x= -7

y= -1

Explanation:

6x + 20y = -62

(3x - 9y = -12) * (-2)

6x + 20y = -62

-6x + 18y = +24

0x+38y= -38

y= -1

replace y in any of the 2 equations

ill replace it in this once since it's easier

3x - 9y = -12

3x -9(-1)= -12

3x +9=-12

3x= -12-9

3x= -21

x= -7
