Solution

Solving each inequation: 1 Mark each
Solution on number line: 1 Mark

Given:2x3<x+23x+5,xϵR
First, we take 2x - 3 < x + 2
2xx<2+3
[Transposing the terms]
x<5 ...(i)
Now, x+23x+5
253xx
32x
1.5x ...(ii)
From equations (i) and (ii), we get 1.5x<5
Solution set is {x:1.5x<5,xϵR}
Graph of the solution set is as follows:
