Compare the following linear equations with the general form of the linear equation in two variables and hence determine the values of \(a\), \(b\) and \(c\).
 
1. -4x+11y=-21
 
The values of  \(a =\) i \(b =\) i and \(c =\) i
 
 
2. 55y-28z=94
 
The values of  \(a =\) i \(b =\) i and \(c =\) i
 
 
3. 103=108x-107z
 
The values of  \(a =\) i \(b =\) i and \(c =\) i
