Answer 1

You need to create and solve a system of equations.

Answer 2

Assume years before maturity is x and years after maturity is y.
x+y=220
900x+2200y=289,000
The answer to the question would be the value of x that makes both those equations true.

Answer 3

Do you know how to solve a system of equations?

Answer 4

Well for the question you are trying to solve, you have to find the values of x and y that make both equations true. You can do that in three ways: graphing, substitution, or elimination. Do you know any of those?

Answer 5

Okay. What would you do then?

Answer 6

I don't understand what you are saying there. Perhaps you can show the work you are trying to do.
