Answer 2

Answer:

The number is 19

Step-by-step explanation:

Given : Expression "48 is 9 less than 3 times a number."

We have to find the number.

Consider the given expression "48 is 9 less than 3 times a number."

Let the number be x.

Then the expression can be  written mathematically as

48 is 9 less than 3 times number x

9 less than 3 times number x = 3x - 9

then 48 = 3x - 9

adding 9 both sides, we get,

48 + 9 = 3x

57 = 3x

divide both side by 3,

we have,

x = 19

Thus, the number is 19.
