We can write this expression as 10 - 4 = 9 - x

10 - 4 = 9 - x

6 = 9 - x

6 - 9 = 9 - x - 9

-3 = -x

-3/-1 = -x/-1

3 = x

Hope This Helped! Good Luck!

It would be 3 because 10-4=6 and 9-3=6 you really just need to find the number that will lead to the same answer as the other

What point is on the graph of every direct variation equation

Alexeev081 [22]

Answer: The point (0,0)
This point is also known as the origin

The reason why is because every direct variation equation is of the form y = k*x
where k is some fixed number

If we plugged in x = 0 it leads to y = k*x = k*0 = 0. So (x,y) = (0,0)
