For this case we have the following functions:

To find the algebraic solution we must equal both equations.
We have then:

Clearing x we have:

Then, the ordered pair solution is:
Answer:
(x, y) = (2/3, 2)
See attached image.
You would just need to make an inequality from the description. You would make "x" the number. The answer would be "x-4>-1"
The answer to this question is 60.
