A Clue For You


The goat and the third pig weigh 89 pounds together. The goat weighs 41 pounds more than the pig. So if p stands for pig then the goat weighs p + 41, and together they weigh 89 so:
pig + goat = 89
p + p + 41 = 89
once you find the value of p, the goat will weigh that number plus 41.
