The expression will be x=y-4
What is less than expression?
The less than expression implies that one number x is lower than another number b by some constant d i.e. it implies that b is greater than a. If we subtract a from b it will give the constant d.
Here, given that,
x is 4 lesser than a number,
let's assume that number is y
from the above, it is clear that As y is greater than x, if we subtract 4 from y we will get x.
so the expression can be written as
y-x=4
⇒x=y-4
Therefore The expression will be x=y-4.
