Actually, I don't really think that you can simplify it, because if you convert them into fractions, there all over 1 and you can't simplify it. You can simplify it if it's:
5 plus 7 DIVIDED by 3. That was when you divide the 12 by 3 in fraction form, the 3 and one switch, and u can simplify 3 into 1 and 12 into four, so there by the answer is 4. (Sorry if confusing)
The answer to 5 times 3 is 15. This is so because if you add 5 plus 5 plus 5 , or 3 plus 3 plus 3 plus 3 plus 3, your answer would be 15. :)

You take 4 times 5 which is 20 then 3 plus 2 which is 5. Add 20 plus 5 and you get 25. That's the answer.
I think you mean 3 times 4...?
5(5x - 3) = 5(3x + 7)There is no need to distribute, simply divide both sides by five5x - 3 = 3x + 7subtract 3x from both sides2x - 3 = 7add 3 to both sides2x = 10divide both sides by 2x = 5

5 times 7 divided by 5 plus 3 minus 4 is 6.
3 x 5 + 3 = 18
