ANYONE GOOD AT ALGEBRA? please help :)

The first answer is beautifully precise and explained quite well. My compliments to the prof.

ldrosophila

si=r(6+i)^n -6
si+6 = r(6+i)^n
(si+6)/((6+i)^n) = r

Since there is only one r, you need to separate all the other stuff from around the r, paying attention to order of operations to keep the right things together.

First multiply both sides by i, cancelling out the i on the right side. Then add 6 to both sides, cancelling out the 6 on the right side. Then multiply by 1/(6+i)^n on both sides, cancelling it out on the right side and leaving only r.

I think it may be more complicated on that, depending on how the problem is supposed to read. OP originally posted

s=(r((6+i)^n-6))/i

followed by

s=r(6+i)^n-6) then that all over "i" as a fraction

In the second version, there is one too many ")". In the first, if accurate, the entire ((6+i)^n-6) would be multiplied by "r", preventing you from simply adding 6 to both sides of the equation.

If I'm incorrect, please let me know. I'm blonde and it's still early.

ETA: If it IS supposed to be written the way you interpretted it, I agree with your math completely.

That's what got me stuck because I kept trying to multiply the R, and started to FOIL the 6+i till I realized the exponent was N!

I did the same thing at first. If the way she wrote it is correct, it should be r = (si)/((6+i)^n -6)

R = Pie?

Apparently I'm not. I tried to solve the problem to see if I'm even qualified to give you instructions.............NOPE. Good luck.

i would like to thank everyone who tried and help me very nice of you. i knew i would get some negative comments but that's okay i understand that's not what this site is made for but almost everyone on here is so nice that's why i decided to ask.


thanks again everyone
