數學5識做-]]幫手]]]簡易方程=3=!! 仲有兩題-口-

98/4+97/4+88/4+ X/4=95
(98+97+88+X)=95*4=380
283+X=280
X=380-283=97

I guess:
X (1-1/5-1/3)=200
X(14/30)=200
X=200*30/14=428+4/7

X (1-1/5-1/3)=200X(7/15)=200X=200*15/7=428 4/714/30 無約簡

sorry 睇錯樓下先ｏ岩X (1-1/5-3/5)=200麻煩你將分數以　１／５　來表達會清楚一些的

(98+97+88+x)/4=95
283+x=4*95
x=97

(1-1/5-3/5)x=200
1/5x=200
x=1000

I don't know what are you saying?can you speak it more clearly?

唔明
不過我諗都好似寫佐個答案係果到
