How do you simplify $3(h - 5)$?

Hint:To solve this question, we need to multiply the number \[3\] inside the bracket. And then equate the equation to zero. Then bring the constant term to the right side. And now we are able to simplify this question and we will get the value for $h$.

Complete step by step solution:
Let us consider the given question
$3(h - 5)$
Equate the given equation to zero we get,
$3(h - 5) = 0$
Multiply the number \[3\] inside the bracket we get,
$(3h - 15) = 0$
Bring the number $ - 15$ to the right-hand side, it becomes $ + 15$
$3h = 15$
$
h = \dfrac{{15}}{3} \\
h = 5 \\
$
This is the required answer.

Note: There are two ways to reduce the more than one operation used equation, one is simplification and approximation. In simplification, we get the exact value for the variables. But in approximation, we get the approximate value.
