what’s the solution of this equation

Answer 1

Write the above sets in roster form 

Write the above sets in roster form We have, A={1,2,3,4,5} and B={4,5,6,7}

Write the above sets in roster form We have, A={1,2,3,4,5} and B={4,5,6,7}From Ven-diagram, A−B={1,2,3} and B−A={6,7}

Write the above sets in roster form We have, A={1,2,3,4,5} and B={4,5,6,7}From Ven-diagram, A−B={1,2,3} and B−A={6,7}Clearly A−B=B−A
