Question 1166243
<font face="Times New Roman" size="+2">


For part d, you only have half of the answer.  The question is: What are Joan's age<b><i>s</i></b> in three years?  One way to express it is, as you wrote *[tex \Large 2\,+\,2(g\,+\,3)], but the other way is just adding three to what you said is her age today, namely *[tex \Large 3g\,+\,3].


Now that you have two different ways to express Joan's age in three years, you can set these two expressions equal to each other to make the equation required in part e.  The numbers you have are correct.
