Question 67820
Luke has $5.00 more than Sam, together they have $73.00. How much does each have. Explain the equation. 
--------------
Start word problems by symbolizing the unknows.
Let amount Sam has be "x" dollars.
Then Luke has "x+5" dollars.
---------------------------
Then try to write an equation involving the variables.
Sam + Luke have 73 dollars
x + (x+5) = 73
Then solve for the variable.
2x+5=73
2x= 68
x=34 
Then interpret the results.
Sam has x=34 dollars
Luke has x+5=34+5=39 dollars

Hope this helps.
