Which would not be a step in solving 3x + 1 + 2x = 2+ 4x?
valina [46]
Well here is how you solve.

You first combine like-terms.
3x + 1 + 2x = 2 + 4x
5x + 1 = 2 + 4x
Then you isolate the variable by subtracting 1 from both sides.
5x = 1 + 4x 
Then you do the same with 4x.
1x = 1
Now divide.
x = 1
Now I know this isn't the exact answer but if you look at the options you have, one of those shouldn't be shown, then that would be your answer. I hope this helps love! :)
