解英文數一條

中文翻譯:

愛德華把60粒波子分成兩份. 如果小份波子數目的7倍等如大份波子數目的3倍, 求小份波子數目.

Let y be the number of marbles in the smaller group, then (60-y) be the number of marbles in the larger group.
設y是小份波子數目, 則(y-3) 是大份波子數目

7y = 3 (60-y)
7y = 180 - 3y
10y = 180
y = 18

Therefore, the number of marbles in the smaller group is 18.
因此, 小份波子數目是18粒

Let x be the numbers of marble in the smaller group
then (60 - x) i sthe number of marble in the larger group
thus, 7x = 3(60 - x)
7x = 180 - 3x
10x = 180
x = 18

the number of marble in the smaller group is 18

愛德華劃分60塊大理石成二個小組。 如果7倍大理石的數量在更小的小組是相等的到3乘那在更大的小組， 看到大理石的數量在更小的小組。
7x=3(60-x)
7x=180-3x
10x=180
x=18

let x be the number of marbles of small group
then number of large group is 60-x

7x=3(60-x)
7x=180-3x
10x=180
x=18

therefore , no of small group is 18

Edward divides 60 marbles into two groups. If 7 times the number of marbles in the smaller group is equal to 3 times that in the larger group, find the number of marbles in the smaller group. !
