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
