15 Mins : Introduction to first-order differential equations & idea of homogeneous form (dy/dx = f(y/x))
15 Mins : Method of reduction – when equation not homogeneous, use substitutions (e.g., y=vx+c) to make it homogeneous
15 Mins : Solved Problems (one directly reducible, one with substitution)
05 Mins : Summary & key steps (check → substitute → solve as homogeneous)
