Answer:
Step-by-step explanation:
we have : lines 2 x + 4 y = 0 and 2 x + y = 10
Let ,
2 x + 4 y = 0............. (1)
2 x + y = 10...............(2)
solve these equations for x and y
Now subtract (2) from (1) ,we get
3y=-10
⇒y =
Put the value of y in (1) , we get
2x+4() = 0
⇒2x=
⇒x=
∴ Point of intersection is .
Hence,the x-coordinate of that point is .
