Answer: 1st question• (-3, -45)
2nd question• x= -3
Step-by-step explanation:
just did it on edge
Cows : sheep = 5 : 4
5x + 4x = 648
9x = 648
x = 72
5x = 5 * 72 = 360
4x = 4 * 72 = 288
There are originally 360 cows and 288 sheep.
2/3 of the sheep are sold. That means that 1/3 of the sheep are left.
1/3 * 288 = 96
96 sheep are left.
x cows were sold.
(360 - x)/96 = 3/1
360 - x = 288
-x = -72
x = 72
72 cows were sold
