I'll do the first one to get you started.


2%2F5+-+3%2Fx+=+1%2F%285x%29+ Start with the given equation.


2x+-+15+=+1+ Multiply EVERY term by the LCD 5x to clear out all the fractions.

2x=1%2B15 Add 15 to both sides.


2x=16 Combine like terms on the right side.


x=%2816%29%2F%282%29 Divide both sides by 2 to isolate x.


x=8 Reduce.

Answer:

So the answer is x=8
