For #1:
x-3=-14
Add three to the -3 and that cancels out. Add three to the negative 14 and that makes negative 11. Therefore x=-11
For #2:
m+1/2=-3/4
Subtract 1/2 from 1/2, that cancels out, subtract 1/2 from -3/4 that equals -1 1/4. Which means that m=-1 1/4
For #3:
-15x=105
Divide by -15 under the -15x and the 105. 105 divided by -15 is 7, so x=7.
For #4:
x/6=9 Translates into x/6=9/1 so 1 goes into 6, six times so 6x9=54 so x=54.

Why don't you turn off your computer and get a pencil and paper. Instead of asking for the answers, you should be trying it on your own. How do you know your getting the right answers from people here. If you don't know how to find the solution, ask your school for extra help.

Are you serious? If you can't do those on your own you need to ask your teacher for some help. You shouldn't be asking strangers for the answers
