Ответ:
12
Step-by-step explanation:
There are 18 pants and the pants are either blue or black. If we represent blue pants as B and black pants as b, this means that:
B + b = 18 (1)
We are told that there are 6 more blue pants than black pants. Hence:
B = 6 + b
=> b = B - 6 (2)
Putting (2) in (1), we have:
B + (B - 6) = 18
=> B + B - 6 = 18
2B - 6 = 18
2B = 18 + 6 = 24
=> B = 24/2 = 12
This means that there are 12 blue pants.
