Asked by Lily

How do you make x the subject of an equation with fractions on each side? For example: v/7x=w/?

When you are manipulating expressions, the most important thing to remember is that whatever you do on one side of the =, you must do the same on the other side. In this case if there are fractions on both sides, you should flip it or in a more mathematical sense, find the reciprocal. v/7x=w/y would become 7x/v=y/w Then you can just take v to the other side by multiplying both sides by v giving you: 7x=vy/w and finally dividing both sides by 7 you get x=vy/7w

Your question is not clear and incomplete but if you mean (v/7x) = (w/y) Easiest way is to flip both sides upside down so (7x/v) = (y/w) Multiply both sides by v/7 Such that (v/7)(7x/v) = (yv/7w) so you get x= (yv/7w)
