which one do you minus or subtract from the equation?

3x = 7 - 4x

The first thing you need to do is get the unknowns on one side of the equation. You also need to change the sign of the part you move.

3x + 4x = 7

7x = 7

x = 1

I answered my own question is this right? 3x=7-4x 3x+4x=7-4x+4x

7x=7 7divided by 7 is one

Right! :-)
