Question

Solve and graph the solution set of:

2x – 9 < 7 and 3x + 9 ≤ 25, x ∈ R

Solution

`2x - 9 < 7 and 3x + 9 <= 25`

`2x  > 16 and 3x  <= 16`

x < 8 and x <=  5 1/3

∴ Solution set = {x <= 5 1/3, x ∈ R}

The required graph on number line is:

  Is there an error in this question or solution?
