Question 1141016
.
<pre>
From the condition, you have these two equations


G + L = 97     (1)

L = 3G + 5     (2)


Substitute expression (2) into equation (1) to get


    G + (3G + 5) = 97.


Simplify and solve for G


    4G + 5 = 97

    4G = 97 - 5

    4G = 92

     G = 92/4 = 23.


<U>ANSWER</U>.  Gary is 23 years old.  Larry is  3*23+5 = 74 years old.


<U>CHECK</U>.  23 + 74 = 97.    ! Correct !
