Question

Solve the proportion 4/x=8/(x-3)

Answer 1

X=-3

Explanation:

Solve it like any other two step equation.

But first we have to have x on its own to get what the x value is

Answer 2

x=-3

Explanation:

4/x=8/(x-3)

We can solve this using cross products

4 ( x-3) = 8x

Distribute

4x -12 = 8x

Subtract 4x from each side

4x-4x-12 = 8x-12-4x

-12 =4x

Divide each side by 4

-12/4 = 4x/4

-3 =x
