Question

The solution to a system of linear equations is (-3,-3). Which system of linear equations has this point as its solution? A. x-5y=-12 and 3x+2y=-15 B. x-5y=-12 and 3x+2y=15 C. x-5y=12 and 3x+2y=-15 D. x-5y=12 and 3x+2y=15

Answer 1

This problem can be solved in 2 ways, by solving each system or by evaluating the solution in each system.

I prefer the second since it is faster, at least for me.

After evaluating, the answer is C.
