Answer:
z = 4
Explanation:
There are an infinite number of equivalent equations. Any of them can be found by making use of the properties of equality.
You can divide both sides by 1.5 to get ...
1.5z/1.5 = 6/1.5
z = 4
__
You can add something to both sides:
1.5z +q = 6 +q
__
You can apply some function to both sides:
arctan(1.5z) = arctan(6)
