Answer:
DUE= {0,10,12,18,19}
Step-by-step explanation:
The union of two sets is a set which contains all the elements of both the sets. thus DUE= {0,10,12,18,19}

so if x = -1, let's plug that in the second equation
-5(-1)+y = 5
5+y = 5
y = 0
Just because you flip and 8 does not mean it turns into an infinite sign, but it does definitely look like it :)
