rewrite an equation in terms of a variable
Hi, Is there a way to get the calculator to rewrite an equation in terms of a variable.
if I have x/(4*Y)=5, can it write y = x/20. I'm trying to rewrite an equation with lots of variables to solve for 1 and on paper i keep missing a step.

In the CAS view, simply use the solve() command. For example,

solve(x^2+2*y=3,y)

You may possibly need to delete the x and y variables: purge(x,y)
