Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
I am guessing you meant if 2x equals 15. First, to solve the equation, divide both sides by 2. So x equals 7.5.
Now substituting for x in 3x-4, we multiply 3 by 7.5 and get 22.5. Finally, we subtract 4 to get the answer: 18.5
zero
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
Yes. Before using the polynomial for any productive purpose, it would have to be cleaned up and simplified. In that process, the +3x4 and -3x4 would go away, and the highest-order term remaining would be the 4x3.

2x-17=13 2x=30 x=15
3x4=12-4=8

No 3 goes into both 12/15 = 3x4/3x5 = 4/5
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
3x1=3 3x2=6 3x3=9 3x4=12 3x5=15 3x6=18

3 is the smallest whole number that can be multiplied by another whole number and result in 9 (3x3) 12 (3x4) and 15 (3x5).
