Step-by-step explanation:
Given inequality is 3x – 5 < x + 7
=>3x – 5 < x + 7
On adding 5 on both sides
=>3x – 5 + 5 < x + 7 + 5
=>3x - 0 < x + 12
=>3x < x + 12
On subtracting x on both sides
=> 3x - x < x - x + 12
=>2x < 0 + 12
=>2x < 12
on dividing by 2 on both sides
=>2x/2 < 12/2
=>x < 6 , x belongs to W
The solution set ={0,1,2,3,4,5}
