If 2x +3y =0 and 4x - 3y =0, then x+y =a)0b)-1c)1d)2​

Answer»

ANSWER:

Option a

Step-by-step explanation:

2x +3y=0\\\\2x=-3y\\\\

x=\frac{-3y}{2}                                  ................ (equation 1)

4x-3y=0\\\\

(from equation 1)

4(\frac{-3y}{2})-3y=0\\\\2(-3y)-3y=0\\\\-6y-3y=0\\\\-9y=0\\\\y=0

PUTTING the VALUE of y in equation 1

x=\frac{-3(0)}{2}\\\\x=\frac{0}{2}\\\\x=0

thus x + y = 0 + 0 = 0
