Given :
The equation below can be used to determine I (simple interest) on a loan as follows :
...(1)
P is principal, r the rate of the loan, t is the length of the loan in years.
We need to find the equation to solve in terms of r. We can find the value of P.
Dividing both sides of equation (1) by rt. So,
So, P can be solved as : .
The value of x is 17.6. She should have added 5.4 on both sides to get the correct value of x. Then the correct option is A.
<h3>What is the linear system?</h3>A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Kaitlyn solved the equation for x using the following calculations.
and she did the calculation will be
The mistake she did in this equation is the plus sign is removed between the -5.4 and x. And she subtracted 5.4 from 12.2.
The correct solution of the equation is to add both sides 5.4. Then we have
