4x - 5
_____    =4
3-7x

In word terms it would be 4x minus 5 divided by 3-7x = 4 and x cannot be three-sevenths

Hi Brandi,

I would first multiply both sides by 3 - 7x to get

which simplifies to

4x - 5 = 12 - 28x

Add 5 to both sides to get

4x = 17 - 28x and then add 28x to both sides

32x = 17 Finally divide both sides by 32 to get the result

x = 17/32.
