or you could just go (x3)(x7) = (x5)(x+2) + (x5)

\[\frac{x3}{x5}=\frac{x+2}{x7}+1\] \[\frac{x3}{x5}\frac{x+2}{x7}1=0\] \[=\frac{(x7)(x3)}{(x7)(x5)}\frac{(x5)(x+2)}{(x5)(x7)}\frac{(x5)(x7)}{(x5)(x7)}\] \[=\frac{(x7)(x3)(x5)(x+2)(x5)(x7)}{(x7)(x5)}\]

What are you having problems with exactly? do you know how to simplify equations at all?

(x3)(x7) = (x5)(x+2) + (x5) = x^(2)  10x + 21 = x^(2)  3x  10 = Im sure you can solve it from here but if you dont know how I got (x3)(x7) = (x5)(x+2) + (x5) from your original problem then say so

have u understood how to solve this problem???

x^(2)  10x + 21 = x^(2)  3x  10 = 10x + 3x = 10  21 = 7x = 31 x = 31/7 = x = 31/7

that is your answer the rest of the people who attempted this problem need a refresher on algebra and solving equations or they just did things the long way

yes please... im not the sharpest knife in the drawer when it comes to mathematics!

well first you always want to bring all x terms into the numerator so to do this I multiplied both sides of the equation by (x5) and (x7) so (x3)(x5)(x7)/(x5) = (1 + (x+2)/(x7)) * (x5)(x7) = (x3)(x7)(1) = (x5)(x7) + (x5)(x7)(x+2)/(x7) = (x3)(x7) = (x5)(x7) + (x5)(x+2)(1) = (x5)(x7) + (x5)(x7)(x+2) = (x5)(x7) + (x5)(x+2) = Now expand everything Looks like I made a mistake :S

ugh my brain it is dead. (x3)(x5)(x7)/(x5) = (1 + (x+2)/(x7)) * (x5)(x7) = (x3)(x7)(1) = (x5)(x7) + (x5)(x7)(x+2)/(x7) = (x3)(x7) = (x5)(x7) + (x5)(x+2)(1) = (x3)(x7) = (x5)(x7) + (x5)(x+2) Now expand and simplify to get the answer

collect all x terms on one side of the equation and move all plain numbers on the other side of the equation

this problem is quadratic so yeah there are two solutions https://www.wolframalpha.com/input/?i=%28x3%29%28x7%29+%3D+%28x5%29%28x7%29+%2B+%28x5%29%28x%2B2%29
