Question

Solve the following system:
-x-8y=-7
2x+8y=6

Answer 1

-1,1

Explanation:

Answer 2

Explanation:

If you add the equations together, the y terms are eliminated.

-x -8y = -7

2x + 8y = 6

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

x + 0y = -1

x = -1

plug the value of x into one of the equations and solve for y:

-(-1) - 8y = -7

-8y = -8

y = 1

(x,y) = (-1, 1)
