WebFirst, let us clear out the "/3" by multiplying each part by 3. Because we are multiplying by a positive number, the inequalities don't change: −6 < 6−2x < 12. Now subtract 6 from each part: −12 < −2x < 6. Now divide each part by 2 (a positive number, so again the inequalities don't change): −6 < −x < 3. WebConsider the same example above. If the element 4 4 is removed from the set B B, solve for (i), (ii), (iii) as well. (i) Since there is no common elements in sets A A and B B, then A \cap B = \phi A∩B = ϕ or A \cap B = \ { \} A ∩B = {}. (ii) Because the element 4 4 is no longer repeated, then A \cup B A∪B remains the same.
