### Instruction:
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?

### Response:
 ให้ R = จำนวนน้ำของโรมัน
รีมี = 3R + 1
4R + 1 = 33
4R = <<32=32>>32
R = <<8=8>>8
รีมี = (3 * 8) + 1 = <<3*8+1=25>>25
รีมีใช้น้ำ 25 แกลลอนในการอาบน้ำ
