Question

Billy's age is 3 more than twice her friend myka. The sum of their ages is 45. How old is each?

Answer 1

Billy's age is 27 and Myka age is 18.

Explanation:

Given: Billy's age: 3, more than twice her friend myka. The sum of their ages is 45.

To Find: The age of Myka.

Solution:

• Assume the number to be 'x'.
• Billy's age: $3x$.
• Myka's age: $2x$.
• Calculating with the sum of their age, $3x + 2x =45$.
• which gives $5x=45$, Finally we get $x = 9$.
• Substituting the x values in the above equation we get,  
• Billy's age:   $3(9)=27$.
• Myka's age:   $2(9) = 18$.
• Hence 27 and 18 are the age of Billy and Myka which has the total sum of 45.
