Answer:
x=1
x=11
Step-by-step explanation:
In the first one you would move the 12 to the other side of the equal sign making
-3x=-3
Then you would divide both sides by -3
For the second one you would combine the -4x and the 6x making
2x-8=14
You would then move the -8 to the other side of the equal sign to make
2x=22
Then divide both sides by 2
