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.
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.
