The student council at Centerville High School is raising money by selling hot apple cider and hot chocolate at this week's games. They sold 25 apple ciders and 31 hot chocolates at the football game, raising a total of $143. They raised $176 at the soccer game by selling 58 apple ciders and 20 hot chocolates.

• 25x+31y=143

  58x+20y=176

• 58x+20y=176

  25x+31y=143

• 58x+25x=176

  31y+20y=143

• 143x=176

  58x+20y=25x+31y
