To find out what z is, you have to work backwards. In this case, divide -77.5 by 15.5 to get the value of z, like so:
-77.5/15.5 = -5
To check, plug in -5 for z to see if it's correct:
15.5*-5 = -77.5
z = -5 :)

Hi there!
Step 1: Divide both sides by 15.5,
z = -77.5 / 15.5
Step 2: Do the division.
-77/5 / 15.5 = -5.
z = -5
Hope this helps! ♥♥
