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
