Answer:
0
Step-by-step explanation:
just multiply and bring the numbers to the other sides and both equal 0
Answer: depends (read explanation)
Either 0=0 (doubt) or:
Z= -3
Step-by-step explanation:
1.Assuming that whole line is the equation:
Group like terms. Put all z terms on one side and normal numbers on the other.
There are brackets so remove them first.
Z-3z-6=-6-2z
-2z+2z=-6+6
0=0
2. If you started the question already and got to -6-2z=0:
-6=2z
Z=-6/2
Z=-3
