Substitution:
6y + 5x = 8
x + 3y = -7
x = -3y + 7
6y + 5(-3y + 7) = 8
6y - 15y + 35 = 8
-9y + 35 = 8
-9y = -27
-y = -3
y = 3
x = -7 + 9
x = 2
y = 3
x = 2
Option A
The simple interest earned is $ 105
<em><u>Solution:</u></em>
Given that, $300 at 5% annual interest for 7 years
Therefore,
Principal = $ 300
Rate of interest = 5 %
Number of years = 7
<em><u>The simple interest is given by formula:</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 formula,</u></em>

Thus simple interest earned is $ 105
Answer:
y=-2x+4
Step-by-step explanation:
If your goal was to write it in slope intercept form, heres your answer.
Otherwise , x=-y/2+2
Like this variation of the problem! :)
We calculate the future value of the 6 annual deposits of $1500 at 8%:
F=1500(1.08^6-1)/(0.08)=11003.89
Since the last payment is due on the day of withdrawal, he would have paid $1500 to get back $11003.89, i.e. with an excess of 1003.89.
Therefore his last payment is 1500-1003.89=$496.11
