Thread: Algebra equation, is this possible to solve ? Where to start?

Hi,

I would like to know if this is possible to solve ? Is there enough data ?

C1 - C2 = 750 euros
J1 = C1 * 8/12 * 0,06
J2 = C2 * 6/12 * 0,04
J1 = 2,5 * J2

What I've done so far was,

J1 = 2,5(C2 * 6/12 * 0,04)
J1 = 2,5( 0,24C2/12 )
J1 = 0,6C2/12

12J1 = 0,6C2

C2 = 12J1/0,6


Now I'm thinking about getting C1, by doing J1 = C1 * 8/12 * 0,06 and so on. But I dont know if this is the right way to work it.

Thanks,

any sugestion is appreciated!

I don't know what exactly you're trying to solve but I shall give you a method that can be used to solve for all the unknowns C1, C2, J1, and J2.

First I multiply out the fraction and decimals for J1 and J2.




We know a constant value: . To put it into this format, try:



Simply substitute and into this equation. You can now solve for as it's the only variable left.

With you can solve for with

well one way to solve it anyway...

Thanks a lot! I understood it very well, this helped me and teached me a lot!

I tought this wouldn't be possible to solve. Thanks for your time Gusbob and bigwave!
