Hope this helps, although I am not a 100% sure it is correct :)
Answer:
m=7 z=-12
Step-by-step explanation:
expand brackets:
8m+24=5m+45
Change sides:
8m-5m=45-24
3m=21
<u>m=7</u>
<u />
<u>z-6</u> = <u>3</u>
2z 4
Coss multiply:
4z-24=6z
4z-6z=24
-2z=24
Divide both sides by -2:
z=-12
I'm not sure what the question is but to get the mean you add up all the numbers and divide them by the amount of numbers there are.
