I would just start by moving x to one sides of the equation.
So I would take subtract -3/4x on both sides, leaving
5/8=4x - 3/4x

What would you do next?

anonymous · Answer

subtract 3/4x from 4x and get 5/8 = 3 1/4x??

anonymous · Answer

So you can leave it as 5/8=13x/4

Now multiply both sides by 4 which leave you with.....

5/2 = 13 x

Now to get x on it's own you divide both sides by 13.

x = _____?
