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

For what value of x would the quotient 3x4 plus 6x3 3x2 not make sense?
zero
What is 3x4 plus 5x3 plus x2 - 5 divided by x 2?
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
Is the degree of the polynomial 3x4 plus 4x3 - 3x4 plus 5x plus 1 is 3?
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.
