大和尚為x,小和尚為y
3x+1/3 y=100 ①
x+y=100 ②
由②得,y=100-x ③
把③代入①,得
9x+100-x=300
x=25
把x=25代入③,y=75
3x+1/3 y=100 ①
x+y=100 ②
由②得,y=100-x ③
把③代入①,得
9x+100-x=300
x=25
把x=25代入③,y=75

let no. of 大和尚 be x
no. of 小和尚 = 100-x
3x + (100-x)/3 = 100
9x + 100 - x =300
8x = 200
x = 25
no. of 大和尚 = 25
no. of 小和尚 = 75
no. of 小和尚 = 100-x
3x + (100-x)/3 = 100
9x + 100 - x =300
8x = 200
x = 25
no. of 大和尚 = 25
no. of 小和尚 = 75
