Hi there!
[tex] \frac{x}{2} - \frac{x}{4} = 6[/tex]
To get rid of the fractions you have to multiply by 4. Multiplying by 2 does not work, because of we do that, we can't get rid of x / 4. Hence, multiply the entire function by 4
[tex]4 \times \frac{x}{2} - 4 \times \frac{x}{4} = 6 \times 4[/tex]
[tex]2x - x = 24[/tex]
[tex]x = 24[/tex]
Therefore, the solution to this equation is x = 24. We've found this solution by multiplying the entire function by 4 and then we've collected terms.
