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

-x + y = 12

x + 2y = 3

a. (7, 5)

b. (5, -7)

c. (-7, 5)

d. (-7, -5)

e. none of the above

This question wants you to find the point of intersection of the two lines, provided they're not parallel.

Solve

-x + y = 12

x + 2y = 3

If you add them together you get

3y=15 so y=5, put that in either equation and solve for x. Try the first one

-x + 5 =12 so -x = 7 or x=-7

The point would be x=-7 and y=5
