Remember, you can do anything to an equation as long as you do it to both sides
and when multiply or divide by a negative in inequalities, flip the direction of the sign
12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4
-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4

B={d, e, f, g}
C={a, d, e, j}
given
(A∩B)∪C
or,[{a, b, d, g}n{d, e, f, g}]UC
or,[{d,g}U{a, d, e, j}]
or,{a,d,e,g}
The dot is not filled and it is between the 5 and 6
