Given pair of linear equations are:
2(ax - by) + (a + 4b) =0
2(bx + ay) + (b - 4a) =0
The above equations can be written as:
2ax – 2by + (a + 4b) = 0
2bx + 2ay + (b – 4a) = 0
The pair of linear equations can be written using cross multiplication method as,
x y 1
– 2b a + 4b 2a – 2b
2a b – 4a 2b 2a
half solved in the picture..
