Hi there!
To solve a fractional equation such as this you need to turn both factors into fractions. Here is how to sole it:
1) Turn 4
into an improper fraction by taking the 4 and multiplying it by the 2 in the denominator and putting the result in the numerator plus the 1 that is already there.
4×2 = 8
8+1 = 9
Now makes

2) Now make 6 a fraction by putting it over 1, like so:

3) Now multiply the numerators together first, then multiply the denominators together, like so:
=

4) Now simplify by dividing 54 by 2 to get the final result:
54÷2 = 27
