The product of 3 and a number is the same as 36 less thrice than that same number. Find the number.

Answer 1

Hi Tylar,

Let's use the variable, x , to represent the unknown number.

Then we can represent the words, "the product of 3 and a number" as: 3x

The text, "36 less thrice that same number" as: 36 - 3x

Since these expressions are to be equal to one another, we can write and solve the following equation to find the value of x:

3x = 36 - 3x

Solve:

3x = 36 - 3x

3x + 3x = 36 - 3x + 3x

6x = 36

6x/6 = 36/6

x = 6

The unknown number would be 6.
