a) No Solution
b) z = 3
c) z = 5
d) z = 7

Answer 1

d) z = 7

Answer 2

hey study if your test is multiplie choice you can solve them or you can plug each of the choices in to see if both sides are the same (if they are then that is one solution if not all)
and if both sides aren't the same for all of the choices then chances are is it no solution or none of these
