Question

if x belongs to N find solution set of 3-x greater than 1

Answer 1

Let's call this set A.

A = {x | x€N, 3-x>1}

First off, you gotta solve the inequality to get all those points which satisfies the equation.

3-x>1 => x<2

Now, the allowed values of x in the set defined are restricted to only natural numbers. So, x = 1.

Therefore, the solution set of the equation, named A, is A = {1} :))
