Given the statement:

Five times a number plus two is 17

Determine the number.

Solution:

Let x = missing number.

The given numerical statement can be written as,

5x + 2 = 17

In order to find the number, simply solve for x. The first step is to transpose 2 on the other side of the equation, hence it must be taken to note that whenever a number is transpose the sign changes.

5x = 17 -2

5x = 15

Divide both sides by 5 in order to cancel out 5x.

5x/5 = 15/5

x = 3

Final answer:

x = 3
