Step-by-step reasoning process: Let x be the number of goats. Cows:4 + x. Pigs:2(4 + x) = 8 + 2x. Total:x + 4 + x + 8 + 2x = 56. 4x + 12 = 56. 4x = 44. x = 11 goats.
The question and answer:
Question and answer: A farmer has twice as many pigs as cows, and 4 more cows than goats. If the farmer has 56 animals total, how many goats does he have?
The answer is 11

Step-by-step reasoning process: If Giselle had 20 doves that laid 3 eggs each, the total number of eggs in the birdhouse is 20 * 3 = 60 eggs. If 3 / 4 of the eggs hatched into birds, their total number is 3 / 4 * 60 = 45. In the birdhouse, there are 20 initial doves + 45 new squabs = 65 birds.
The question and answer:
Question and answer: Giselle had 20 female doves in a birdhouse. After a month, the doves laid 3 eggs each. If 3/4 of the eggs hatched, calculate the total number of doves Giselle has now.
The answer is 65

Step-by-step reasoning process: Steven has 3 x 30 = 90 stickers. And, Terry has 90 + 20 = 110 stickers. Therefore, they have 30 + 90 + 110 = 230 stickers altogether.
The question and answer:
Question and answer:
Ryan has 30 stickers. Steven has thrice as many stickers as Ryan. Terry has 20 more stickers than Steven. How many stickers do they have altogether?
