Solve by cross multiplication method 2(ax-by)+(a+4b)=0 2(bx+ay)+(b-4a)

1.	Solve by cross multiplication method 2(ax-by)+(a+4b)=0 2(bx+ay)+(b-4a)=0
Answer» Step-by-step explanation: 2(ax-by)+(a+4b)= 0 eqn1 2(bx+ay)+(b-4a)= 0 eqn2 Multiplying eqn1 and 2 we GET, =4(ax-by)(bx+ay) + (a+4b)(b-4a) =(ax-by) (bx+ay) + (a+4b) + b =by+bx+(a+5b) =2XY+(a+5b)

Solve by cross multiplication method 2(ax-by)+(a+4b)=0 2(bx+ay)+(b-4a)=0

Answer»

Step-by-step explanation:

2(ax-by)+(a+4b)= 0 eqn1

2(bx+ay)+(b-4a)= 0 eqn2

Multiplying eqn1 and 2

we GET,

=4(ax-by)(bx+ay) + (a+4b)(b-4a)

=(ax-by) (bx+ay) + (a+4b) + b

=by+bx+(a+5b)

=2XY+(a+5b)
