Can someone please help me without using a link?

Ricky takes out a $31,800 student loan to pay his expenses while he is in college. after graduation, he will begin making payments of $190.66 per month for the next 30 years to pay off the loan. how much more will ricky end up paying for the loan than the original value of $31,800? ricky will end up paying $ more than he borrowed to pay off the loan.

What would the rule be for the reflection of y=-3

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
