✔ 最佳答案
Let x and y be the number of sweets that Bonnie and Kitty gets respectively.x + y = 60 --- (1)
4x = 3y + 2 --- (2)
From (1), x = 60 - y --- (3)
Subs (3) into (2),
4(60 - y) = 3y + 2
240 - 4y = 3y + 2
238 = 7y
y = 34
∴ Kitty gets 34 sweets.

B+K=60....(1)
4B-2=3K....(2)
where B=Bonnie's sweets, K=Kitty's sweets
now solve (1) & (2)
sub B=60-K into (2)
4(60-K)-2=3K
7K=238
K=34
then, sub K=34 into (1)
B+34=60
B=26
4B-2=3K....(2)
where B=Bonnie's sweets, K=Kitty's sweets
now solve (1) & (2)
sub B=60-K into (2)
4(60-K)-2=3K
7K=238
K=34
then, sub K=34 into (1)
B+34=60
B=26
