Choose the ordered pair that is a solution to the system of equations.

3x - y = 10
-x + y = -4

(3, -7)
(-1, 3)
(3, -1)
(3, 1)



Follow the example I gave in your previous question. I'm not going to do all of them.
You want to eliminate one of the variable and solve. Then substitute into an equation and sovle for the other variable.
If you add the equations together
3x - y = 10
-x + y = -4
you get
2x = 6
Solve for x and substitute into either equation to solve for the other variable.
