Sagot :
the shop had 2 cats because if you minus10 to 2 the answer is 8 and they buy 2 cats so there are 2 cats
Before buying cats, and selling dogs:
Let cats be x
dogs b x + 10
After:
Selling 2 dogs: x + 10 - 2 or x + 8
Buying 2 cats : x + 2
2 (x + 2) = x + 8
2x + 4 = x + 8
2x - x = 8 - 4
x = 4
The shop now have: X + 2
4 + 2
= 6 cats, Final answer
To check how many dogs:
X + 2 = 4 + 2 = 6 cats
X + 8 = 4 + 8 = 12 dogs
The hidden question the dogs are now twice the number of cats
Cats = 6
Dogs= 2 (6) = 12
Let cats be x
dogs b x + 10
After:
Selling 2 dogs: x + 10 - 2 or x + 8
Buying 2 cats : x + 2
2 (x + 2) = x + 8
2x + 4 = x + 8
2x - x = 8 - 4
x = 4
The shop now have: X + 2
4 + 2
= 6 cats, Final answer
To check how many dogs:
X + 2 = 4 + 2 = 6 cats
X + 8 = 4 + 8 = 12 dogs
