z = 1

Explanation:

1. Combine like terms.

#color(red)(6z) color(blue)(- 10) color(red)(- z) color(blue)( + 5) = 0#
#5z - 5 = 0#

2. Add 5 to both sides to isolate the variable (#z#).

#5z - 5 + 5 = 0 + 5#
#5z = 5#

3. Divide both sides by 5 to find #z#.

#(5z)/5 = 5/5#

#z = 1#

That's your answer!
