Question

solve the equation. ((4)/(7 x))+((1)/(2x)) = -((1)/(4))

I'm stumped

Answer 1

\[\frac{4}{7x}+\frac{1}{2x} = -\frac{1}{4}\]

First keep in mind that anything times 1 equals itself, e.g. x*1=x
Also keep in mind that anything divided by itself also equals 1, e.g. 1 = (5/5)

What you want to do is to multiply 1 (in one form or another) by each fraction so that the denominator is the same for all three fractions.
