SHARMA MATHEMATICS (40 Questions) ХС Question. 5 If xe N, find the solution set of the given inequation,5x+ 3s 2x+18 Select from the Answers below​

Answer 1

$\bold\red{ANSWER}$

(i) 5x + 3 ≤ 2x + 18

5x – 2x ≤ 18 – 3

3x ≤ 15

X ≤ 5

Since, x ∈ N, therefore solution set is {1,2,3,4,5}

(ii) 3x – 2 < 19 – 4x

3x + 4x < 19 + 2

7x < 21

X < 3

Since, x ∈ N, therefore solution set is {1,2}.
