I don't get how to do the problem that is attached. Could someone help like break it down in steps for me?
I now know how to do 2 step equations but i am not sure were to start for this 1.
Thanks!
add Z to -10z making it -9z. Then subtract the 1 to bring it over to 10 making it nine. so far the equation should be -9z=9. To get z by its self divide by -9 and 9 divided by -9 is -1 so z=-1.
