Question

Solve each system by elimination. X+6y=-8 7x+2y=24

Answer 1

Answer:

y=-2

x=4

Step-by-step explanation:

equation 1: x + 6y = -8

equation 2: 7x + 2y = 24

To eliminate x first, multiply equation 1 by 7:

7x + 42y = -56

Then subtract the equations from each other:

{ 7x + 42y = -56 } - { 7x + 2y = 24 } = -40y=80

Then we divide both sides by -40 to isolate the y

y = -2

Then we plug -2 into y in one of the equations to find x:

7x+42y=-56

7x+42(-2)=-56

7x-84=-56

7x=28

x=4

Answer 2

Answer:

8x + 8y = 24
