If 3 times a number minus 2 equals 13, what is the number?

The given question is based on a linear equation in one variable.

Answer: If 3 times a number minus 2 equals 13, then the number is 5.

Let's solve the given equation by interpreting the given information mathematically.

Explanation:

Let the required number be x.

Given that, 3 times a number minus 2 equals 13.

3x - 2 = 13

3x = 13 + 2

3x = 15

x = 15 /3

x = 5

Thus, x = 5 is the solution of the given equation 3x - 2 = 13.
