Word problems suck. Now I wish I hadn`t been sick and skipped school that day. Eh. Wanna help me? ><;
The sum of the digits of a two-digit number is 14. If the digits are reversed, the number is increased by 63. What is the number.

Well, how would I write it out?
I notice it`s like t+u=14 or something.
What I dont really get is the "if the digits are reversed, the number is increased by 63". ><;

No typos, it says 63 plain and clear.

I think you made a typo when you typed 63, it should be 36.
59 + 36 = 95
5 + 9 = 14

Well, first try to find information you know. Pick out the facts:
~You know it's a two digit number
~The numbers together add up to 14
~If you switch the numbers with each other the amount is increased to 63.
Next, find numbers that add up to 14, and then switch them and find which ones are increased (go up) to about 63.
If you have been working with negative, and positive numbers lately then there might be a trick. if not, then just go for basic doubles like 7+7 or 5+9.
Does that help?

Ok, I know this is a really long way to solve them, but it's foolproof.
First - we need two single digit numbers, that when added, equal 7.
We have:
9 and 5 (from here, you'll want to increase one and decrease the other - so:
8 and 6
7 and 7
6 and 8
5 and 9
4 and 10 - but that's two digits, so we stop here.
So - 86, reversed, is 68. 86 minus 68 is only about 18 (I think - I don't actually feel like subtracting) ... and we need it to be 63.
77, we can rule out immediately, because it's the same number both ways.
Therefore, it must be 59. 95 - 59 = 36 (I'm going to assume that you typoed... because yeah, I don't think it's possible for it to equal 63. Let me know if I'm wrong.)
I hope that helped, if you need more help, just let me know.

first, think of all the possible number combos that add up to 14, that are composed of one digit. then try them all out

that isn't posibble. the biggest number change you could make is 59-95 and that is only a 36 change. can't happen
