Question
If x ∈ W, then the solution set of the inequation 3x + 11 ≥ x + 8 is
Options
{ – 2, – 1, 0, 1, 2, …}
{ – 1, 0, 1, 2, …}
{0, 1, 2, 3, …}
`{x : x ∈"R",x≥ -(3)/(2)}`
Solution
x ∈ W
3x + 11 ≥ x + 8
⇒ 3x – x ≥ 8 – 11
⇒ 2x ≥ -3
⇒ `x ≥ (-3)/(2)`
⇒ `x ≥ -1(1)/(2)`
Solution set = {0, 1, 2, 3, .....}.
