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.
