I will do 6 & 12
6. 7 with a small 3 to the top right of it.
12. g squred - 18g needs a +81 to get (g-9)^2 so c=81
ok #7 is 9/15 = 3/5
post answers for the others and I will help you if you get them right or wrong, at least give them a shot.

Answer in no. 1 is 3, transpose 5 to the other side, it becomes 6x = 23 - 5. 23 - 5 is 18, then lose the 6. 18/6 is 3, so x = 3. Get it?
The others are easy too, and you SHOULD do your homework. You'll never learn by simply asking for answers. If you really can't understand it, then go and ask some help from your classmates. I'm sure there'll be those who are intelligent and kind enough to help you. If all else fails, then ask your teacher. They're being paid to teach you, remember that.

I'll take the 1st one only. Subtract 5 from 23. Divide the remainder by 6. That'll be x.

I think I speak for everyone on YA.
We are not here to do your middle school math homework. One problem, yes, but not all of it. Get off your godsdamned computer, open a book, buy a calculator, and use your brain.
I can solve these and math is my worst subject. Practically failed it.

This is really easy...Just do your own work. If you honestly don't understand it ask your teacher or get a tutor.
