let the number be x
so X×4 (-7) = 65
4x = 65+7
4x = 72
x = 72 ÷ 4
x = 18
So the value of x is 18
so X×4 (-7) = 65
4x = 65+7
4x = 72
x = 72 ÷ 4
x = 18
So the value of x is 18

4x-7=65
4x=65+7
4x=72
x=72/4
x=18 is the number
Let us prove
18 multiplied by 4 =72
72 diminished by 7 is 65
Hence number is 18 proved.
