Question

ifx€{-3,-2,-1,0,1,2,3} find the solition set of 3x-5_^>-12​

Answer 1

Answer:

Condition : 3x - 5 ≥ -12

⇒ 3x ≥ -12 + 5

⇒ 3x ≥ -7

⇒ x ≥ -7/3

⇒ x ≥  -2.3

Hence values of x that are equal to and greater than 2.3 are solutions of the given condition.

x ∈ { -3, -2, -1, 0, 1, 2, 3 }

Here, the values greater than -2.3 are { -2, -1, 0, 1, 2, 3 }

Hence Solution Set = { -2, -1, 0, 1, 2, 3 }
