solve linear equations with 3 variables that is given by user
<p>i'm trying to figure out how to write down a program in java to solve 2 equations that have 3 variables, which is given by the user:</p>

<pre><code>A11 * X1 + A12 * X2 = B1
A21 * X1 + A22 * X2 = B2 
</code></pre>

<p>numbers are given by user, per say 1 2 3 4 5 6 (for a11 a12 a21 a22 b1 b2)
and the answers are "no solution" "many solutions" "single solution (x1,x2)
i'm stuck.... don't even know where to begin
help?</p>
