sets :
(iv) A4 = {b: b E Z and -7 < 3b - 1 <2}​

Answer 1

Answer:

Equations ( 3 to 5 ) can be rewritten as ( 9 ) B ( 1 - ) 345 = ( 1 - $ ) CuaCostela ... if we subtract ( 9 ) from ( 11 ) , we obtain ( A3 - A , ) e + ( 3A3 - A4 ) = + 2€3C14 . ... We can now obtain Cu by substituting the value of ez given by ( 14 ) into ( 13 ) .
