Question

The sum of 5 and the quotient of a number and 2 is 15. What is the number?

Answer 1

X is the number

 

X/2 is quotient of a number and 2

 

        5 + X/2 = 15

 

Multiply all terms by 2 to eliminate fractions

 

         10 + X = 30

 

                X = 20

 

number is 20

Answer 2

Let a = the number.

 

5 + a/2 = 15

a/2 = 10

a = 20

 

Hope this helps!
