Answer:good for him
Step-by-step explanation:
Rate of interest is 6 %
<em><u>Solution:</u></em>
Given in question that,
simple interest = $ 3240
number of years = 9 years
principal sum = $ 6000
To find: interest rate
<em><u>The simple interest is given as:</u></em>

Where, "p" is the principal
"r" is the rate of interest
"n" is the number of years
<em><u>Substituting the values in above formula,</u></em>

Thus rate of interest is 6 %
Distribute the 2 into the 2x and -y
Then add “like terms” which are 3x and 4x... 3y and -2y
Which then becomes 7x+y
There are no more “like terms” so that is your final answer
The answer is x = 6
