Hint : Divide by a suitable number

The given equation is
$3l = 42$
We need to find the value of $l$.
So we have to divide both sides of the equation by $3$.

On dividing both sides of the equation by $3$ we get,
$\dfrac{{3l}}{3} = \dfrac{{42}}{3}$
$l = 14$
Hence, the value of $l$ is 14.

Note :- In these types of questions where we have to find the value of a certain variable we have to apply algebraic operations on equations like multiplication, division, addition, subtraction to get the value of the required variable.
