I have a homework sheet which I have almost done but there are some parts which I cannot seem to figure out. I will post them here and hope that someone can help me with some of them.

1.Solve for the X-values which make the function true.

X^3+25>10X^2-15X

2. Solve for Y (how do I make Mathcad to solve this for me without having to change "X/A" to the other side myself, but instead that Mathcad will do it?

2X+4=X/A+Y
