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! :)
