What is the result of subtracting the second equation from the first?
2x+7y=-8 - 2x-5y=-1

12y = -7

Step-by-step explanation:

Principal

Step-by-step explanation:

Since, the amount in the simple interest is,

Where, P is the principal amount,

r is the annual rate,

t is the time ( in years ),

Here, r = 3.75 %, t = 6 years,

Thus, By the above explanation,

It is clear that, we need the value of P, that is, principal to find the amount.
