Question

Suppose why varies directly with X. Write a variation equation that relates x and y

Y = 10.4 when X =4

Answer 1

`x = y - 6.4`

Steps :

1. Create an equation

If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

`x - 4 = y - 10.4`

2. Isolate variable X by adding 4 to both sides

`x = y - 6.4`

3. (Optional) Check Answer by plugging given values into the equation

`(4) = (10.4) - 6.4`

4 = 4 is a true statement
