Your question is missing some elements but to answer the question I have to make an assumption.
Assuming that she make a
monthly payment of $75.
The value of an loan at the end of the two year is given by

where PV = $799, r = 7.2% = 0.072 and n = 2 years.
Thus,

If she makes a monthly payment of $75, the number of months it will take her to pay off for her laptop is given by

Step-by-step explanation:
Answer: x=7
ab=21
bc=14
Step-by-step explanation:
ab=3x
bc=2x±7
ac=42
3x±2x±7=42
5x±7=42
5x=42-7
5x=35
to get the value of x you divide 35 by 5x
35÷5x=7
so the value of x is 7
ab=3x
x=7
3x=7×3x
7×3=21
x=7
2x=7×2x
2×7=14
