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.
