4 ko into upper wala sa krdo aur 3 ko into niche wala sa uska bd equation 1st_equation 2nd kro phir X ka value nikl jayega to usko equation 1st m put krke Y ka value nikalo ho jayega phir.

Answer 2

Step-by-step explanation:

2x + 3y = 0 --------(1)

3x + 4y = 5 --------(2)

From eq.(1),

2x + 3y = 0

2x = -3y

x = -3y/2 ----------(3)

Now, by sub. "x" value in eq.(2)

3(-3y/2)+4y = 5

-9y/2 +4y = 5

-9y+8y/2 = 5

-y/2 = 5

-y = 10

y = -10

Now, by sub."y" value in eq.(3),

x = -3(-10)/2

x = 30/2

x = 15

Therefore,

x = 15

y = -10

Hope it helps
