Answer:
the answer is x plus y over x minus y
-|x+3|
its a positive 3 because you move it the opposite way im pretty sure
and it’s negative because it’s pointed down
so the first term is 36500.
after a year, he gets 2375 extra, so
1st year, 36500
2nd year 36500 + 2375
3rd year 36500 + 2375 + 2375
4th year 36500 + 2375 + 2375 + 2375
and so on
so the common difference is 2375, namely the number we add in order to get the following term.
It's too hard for me to show all the work, but you can find a common denominator in 8.
Change 3/4 to 6/8 and -3/2 to -12/8.
Now that all the fractions have the same denominator, you can multiply the whole problem by 8 and cancel out all denominators.
You are left with 6=3x-12
Add 12 to 6 and cancel out on the right side.
18=3x
Divide by 18 by 3
x=6
