Question

What is the solution of the system?

Answer 1

Is it -5,5??

Answer 2

If I got that answer right that means that I finally know how to do these kinds of problems!! wohoo!

Answer 3

Yes, you got it right! Good job!

Answer 4

just draw the graph lol

but you know that it isnt no solutions, since the lines are not parallel
you know that it is not infinite solutions because the lines are not the same
so you have 1 solution because they intersect once

Answer 5

Test-taking skill: some problem solutions can be gotten to most quickly by solving and then looking for the answer among multiple-choices. Some solutions though can be gotten to most quickly by plugging in the answers one by one!
