Homework Statement

I have a formula but i don't know how to get the "X". Example (i need the X): y=1/x => x=1/y.

This is the formula:

(1/3)x + (1/4)y = x/a so can someone explain the answer please

Hi there :)

Put everything which depends on x on one side of the equal sign; everything which does not depend on x on the other side.
On the “x” side, factorize so as to have “something” multiplied by x.
Divide both sides by this “something” :)
