# Going from proportional to equals...

 P: 69 Hi guys, This may well be a very trivial question but it isn't immediately obvious to me.. I know if you have x is proportional to y by adding a constant you can say; x = cy However, if we have x is proportional to y + z, is there a similar 'trick' that can be used? Basically, i have an expression; J(w) $\propto$ [w-w0]^1/2 + [w0 - w]^1/2 and want to set this equal. Thanks in advance!
