<human>:  Roman and Remy took separate showers. Remy used 1 more gallon than 3 times the number of gallons that Roman used for his shower. Together the boys used 33 gallons of water. How many gallons did Remy use?
<bot>: Define a variable ** Let R = Roman's gallons
How many gallons did Remy use? ** Remy = 3R + 1
Write an equation ** 4R + 1 = 33
Simplify ** 4R = <<32=32>>32
Divide by 4 ** R = <<8=8>>8
How many gallons did Remy use? ** Remy used 25 gallons of water for his shower.
