Question

Solving using elimination
-7x-y=-17
7x-5y=-1

Answer 1

x=2, y=3

Explanation:

-7x-y=-17

7x-5y=-1

Add the two equations together to eliminate x

-7x-y=-17

7x-5y=-1

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

-6y = -18

Divide by -6

-6y/-6 = -18/-6

y = 3

Now we need to find x

7x -5y = -1

7x -5(3) = -1

7x -15 = -1

Add 15 to each side

7x -15+15 = -1+15

7x = 14

Divide by 7

7x/7 = 14/7

x =2
