Sam is twice as old as Mary.
Translation:  S = 2M

Mary is one year older then Jim.
Translation:  M = J+1

Jim's age is x.
Translation:  J = x

Write an expression to find Sam's age in terms of x.
Translation:  

1. Use J = x to substitute x for J in M = J+1.

2. Then take what you get M to equal, 
   put parentheses around it,
   and substitute it for M in S = 2M.  

3. Then distribute.

You finish.
