[QUOTE="Mentallic, post: 4584126, member: 144450"] Remember that [tex]a\cdot\frac{b}{c} = \frac{a}{c}\cdot b =\frac{ab}{c}[/tex] (The dot means multiply) so if we multiply [tex]\frac{23}{120x}=\frac{1}{5}[/tex] by the denominator in the left fraction (which is 120x) then we get [tex]120x\cdot\frac{23}{120x}=120x\cdot\frac{1}{5}[/tex] And now we can cancel 120x from the left side because [tex]120x\cdot\frac{23}{120x} = \frac{120x}{120x}\cdot 23 = 1\cdot 23=23[/tex] So we now have [tex]23=\frac{120x}{5}[/tex] Now you can solve the rest in the usual way you've been solving equations. Also, keep in mind that you can have just multiplied through by x rather than 120x. [/QUOTE]
