Question Number 74455 by Mr. K last updated on 24/Nov/19

i f K = (x \in R 2 x - 1 + ∣ 2 x - 1 ∣= 0) a n d

J = (x \in R - x (2 x + 1) ⩽ - 1) f i n d J - K .

K = {x \in R ∣ x ⩽ \frac{1}{2}}

J = {x \in R ∣ x ⩽ - 1 \lor x ⩾ \frac{1}{2}}

J - K = {x \in R ∣ x \in J \land x \notin K} = {x \in R ∣ x > \frac{1}{2}}
