4x=8
x=2
Check: 2(4)+10=18

Let the number be x.
Then:
4x + 10 = 18
Subtract 10:
4x = 8
Divide by 4:
x = 2.

Let that no be x
since 4 times of this will be 4x
so according to given condition
4x+10=18
4x=18-10
4x=8
x=8/4
x=2
So the no is 2.

let the no=x
so as per given condition,we have
4x+10=18
or 4x+10-10=18-10
or 4x/4=8/4
or x=2 ans

4x+10 = 18
-10 -10
4x=8
divide both sides by 4
x=2
