The sum of Molly and Bobby’s ages is 14. If Molly is 5 years older than twice Bobby’s age, how old is each child?

Molly is 11 and Bobby is 3.

Step-by-step explanation:

Let Molly's age be m and Bobby's age be b.

Subtract b from both sides:

(Equation 1)

(Equation 2)

(Both equations are equal to each other as they are equal to m)

Subtract 14 from both sides:

Subtract 2b from both sides:

Divide both sides by -3:

Since , .

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
