Question

Use elimination method to solve for x and y - 8y = -16 6x + 8y = -8​

Answer 1

x =
`-(24)/(7)`

Explanation:

x - 8y = -16

6x + 8y = -8

= 7x = -24

Divide both sides by 7;

x =
`-(24)/(7)`

Answer 2

Step 1: Get rid of y and solve for x by using elimination.

`-8y = -16\\6x + 8y = -8\\\\6x = 24\\\\x = 4`

Step 2: Plug what we found for x in the SECOND equation, then solve for y.

`6(4) + 8y = -8\\\\24 + 8y = -8\\\\8y = -32\\\\y = -4`

Now, we can put both numbers together for our solution.

(4, -4)
