5+4-3=6
is eassy
x + 5 + 4 = x + 9
8+n
To put a plus or minus sign with the digit 5
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)
you just solve. the answer is 5
-5
[(7+3)/(x+4)] / [(x-5)/(2-4)] =[(7+3)/(x+4)] * [(2-4)/(x-5)] =[10*(x-5)] / [-2*(x+4)] =-5*[(x-5)/(x+4)]
19 is the answer to 3 plus 4 plus 4 plus 3 plus 5
1/3 + 3/5 + 7/10 = 49/30 or 119/30
3b -1
It is: -24 simplified
