So what method do you like to use?

Substitution, elimination, or graphing?

I like graphing but my test wants substitution

I see (10,30)

thesmartone · Answer

Are you sure that it is 10?

The 30 is correct.

thesmartone · Answer

Look at the graph a little closer and see where it intersects. It gives you the point where they intersect if you click on it.

You have half of it correct.
