Answer:
12=3x-6 is 6
16=4x+8 is 2
4z+8=40 is 8
5x-7=38 is 9
-3x-9=24 is -11
Step-by-step explanation:
for 12=3x-6 you would get x by itself so first you add the 6 to the 12
you get 18 then you try to get the x by itself so you divide 3x by 3 and divide 18 by 3 as well. So you end up with 6=x. Repeat with every problem
