just do what it says
4 times (a number +5, )which is divided by 7
that number must be 2
4x(2+5)=28
28/7=4

條問題應該係4 times( the sum of a number and 5 )is divided by 7,"is divided by 7"應該係講緊( the sum of a number and 5 )
Let the number be x
4(x+5)=7M ,where M is an integer
x=(7M/4)-5

我諗the sum應該冇可能指一個數掛,試問一個數怎能有總和,總和應該最少指2個或以上既數
