Question

3x+4y=0 aue x-y=0 ki vilopan vidhi

Answer 1

Answer:

3x+4y=0-----(1)

x-y = 0-------(2)

multiplying equation (2) by 4

x×4-y×4=0×4

4x-4y=0----(3)

adding equation (1) and(3)

{3x+4y =0}+{4x -4y =0}

7x =0

x=0-7

x= -7

put x=-7 in equation (2)

-7-y=0

-y=7

y=-7

solution =(x,y)=(-7,-7)

Answer 2

Answer:

3x+4y=0---------(1)

x-y=0-----------(2)

multiplying equation (2) by 4

x×4-y×4=0×4

4x-4y=0-----(3)

adding equation (1) and (3).

{3x+4y=0}-{4x-4y=0}

7x=0

x=0÷7

x=0

put x=0 in equation (2).

x-y=0

0-y=0

-y=0

y=0

solution =(x,y)=(0,0)
