Question

Kym is three times Brandon's age plus 1. Their combined age is 49. How old is Brandon?

Answer 1

Step 1. Use the sentence "Kym is three times Brandon's age plus 1" to find our first equation.

We represent Kym's age with "k" and Brandon's age with "b", so we get for this sentence:

`k=3b+1`

Which represents that Kym is 3 times the age of Brandon plus 1.

Step 2. Use the sentence "Their combined age is 49." to find our second equation:

`k+b=49`

Step 3. Substitute equation 1 (from step 1) into equation 2 (from equation 2).
