The graphs of the lines 2 x + 4 y = 0 and 2 x + y = 10 intersect in a point. What is the x-coordinate of that point?

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 .
