Hi Tracy!
Let the number we are trying to find be called x (boy thats original huh?)
Well then, half that number (x) would be x/2.
3 times that number would be 3x
Finally 10 more than three times the number would be 10 + 3x

One key word in the problem is the word "is".  read this as equal to.

So <Half of a number> <is> <10 more than three times the number>
	x/2               = 10 +3x

Now we have an equation to solve!  x/2 = 10 + 3x <multiply each side by 2>
	x = 2(10 + 30x)
	x = 20 + 6x	<subtract 6x from both sides>
	-5x = 20	<divide by -5>
	x = -4

one of the problems is: half of a number is 10 more than three times the
number.
