We need to solve for .
Step 1: Analyze the first equation
This equation implies that .
Step 2: Substitute into the second equation
The second equation is:
Substitute into this equation: Expanding and combining like terms: [ [(b + c) - (a + b)]x + [(c + a) - (a + b)]y = 0 ]
For this equation to hold, assuming and , we must have:
Step 3: Substitute into the third equation
The third equation is:
