Answer :

Formulating the question into an equation, it is obtained that the number divided by 3 with 19 added equals 36 is 51.

Mathematically, an equation is an assertion that asserts the equality of two expressions. It contains two sides, the left-hand side (LHS) and the right-hand side (RHS), separated by an equal sign (=). The LHS and RHS can be numbers, variables, constants, or more complex mathematical expressions.

Let x be the number.

According to the question,

[tex]\frac{x}{3}[/tex] + 19 = 36

[tex]\frac{x}{3}[/tex] = 36 - 19

[tex]\frac{x}{3}[/tex] = 17

x = 17 [tex]\times[/tex] 3

x = 51.

So, the number is 51.

You do the sum backwards,
36-16=17
17x3=51
Then you check it to make sure,
51/3=17
17+19=36
