Answer:
Step-by-step explanation:
Number of pigs with John = x
Number of pigs with Taylor = x - 7
Number of pigs with Mark = 2x + 6
Total pigs = 459
x + x - 7 + 2x + 6 = 459
x+ x + 2x - 7 + 6 = 459
4x - 1 = 459
4x = 459 + 1
4x = 460
x = 460/4
x = 115
Number of pigs with John = 115
Number of pigs with Taylor = 115 - 7 = 108
Number of pigs with Mark = 2*115 + 6 = 230 + 6 = 236
