Question

1)
i) 2x + y = 0 and 3x - y = 0 combined equation of pair of line​

Answer 1

Answer:

x=0/10

y = 0/-5

Step-by-step explanation:

2x+y=0

3x-y=0

2x = -y

x = -y/2

3x-y = 0

3(-y/2)-y = 0

-3y/2-y=0

-3y-2y/2=0

-5y/2=0

-5y=0*2

-5y = 0

y = 0/-5

2x-y = 0

2x-0/-5=0

2x+0/5=0

10x+0=0

10x=0-0

10x=0

x=0/10

Answer 2

Step-by-step explanation:

Given: 2x+y=0 and 3x-y=0

To find: Find the combine equation of given lines.

Solution:

Tip: To find the combine equation of lines multiply both eqs

$(2x + y)(3x-y) = 0 \\ \\ 6x^2-2xy + 3xy -y^2 = 0 \\ \\6x^2+xy -y^2 = 0$

Final answer:

Combined equation of lines 2x+y=0 and 3x-y=0 is

$\bold{\pink{6x^2+xy -y^2 = 0}}$
