let a be the orange that the fruit shop buy in.
(a+346)5% = 33
a+346 = 33 / 5%
a+346 = 660
a = 660-346
a=314
Therefore,the fruit shop buy 314 orange.
(a+346)5% = 33
a+346 = 33 / 5%
a+346 = 660
a = 660-346
a=314
Therefore,the fruit shop buy 314 orange.

設水果店買入橙x 個
(x+346)x5%=33
x+346x5%÷5% =33÷5%
x+346-346=660-346
x=314(個)
(x+346)x5%=33
x+346x5%÷5% =33÷5%
x+346-346=660-346
x=314(個)

設水果店買入橙Y個。
(Y+346)5%=33
Y+346=33/5%
Y+346=660
Y=660-346
Y=314
所以水果店買入橙314個。
(Y+346)5%=33
Y+346=33/5%
Y+346=660
Y=660-346
Y=314
所以水果店買入橙314個。
