TI-89 Question, Solving In Terms Of

Test Preparation SAT Subject Test Preparation

<p>I know that the solve() function on the TI89 can be used to solve for x, for example solve(x^2-2x+3=0,x) will return the zeros of the quadratic. Is there a way, however, to solve "in terms of" ... like if I had an equation such as: 3b + 4a = 0, could I do solve(3b+4a=0, a/b) so it would rearrange and give me the value of a/b? The regular solve function wouldn't let me do it.</p>

<p>I know that's a pretty simple thing to do algebraically (it would be a/b + 3/4 = 0), but I'd like to have a way to check myself just in case if possible since I tend to make stupid mistakes like that.</p>

<p>Thanks!</p>

<p>I dont think there is a way unless you create a program to do it, but you can solve in terms of a, then in terms of b, and divide the two to get a simplified a/b.</p>

<p>you could plug in a number</p>
