You guys : ) which ordered pair (x, y) is a solution to the following system of equations? {5x+4y=-14} {3x+6y=6} answer choices: a. (-6,4) b. (2/7,18/7) c. (18/7,2/7) d. (6,-2)

There is a long way - but I like the short way!

There is only one correct solution so why not start with A. & D. (the easy answers) and plug them in for your variables and test them.

I started with A and what do you know - it checks out!

{5x+4y=-14}   Put -6 in for x and 4 in for y

-30 + 16 = -14 Is that right? Yes Now try the next equation.

{3x+6y=6}    Put -6 in for x and 4 in for y

-18 + 24 = 6 Is that right? Yes. We are good. Problem solved.

The long way would be to use the substitution method and solve for x and then substitute to find y.
