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.
