Error analysis 3x− 4 = 2x+ 1
3x− 4 − 2x= 2x+ 1 − 2x
x− 4 = 1
x− 4 + 4 = 1 −
4x=−3

In the second to last part, there should have been a 4 added to the right side instead of subtracted, making it x=5 and not x=-3

You put it in a little weird in that part too, watch out for that next time. The 4 that should've been in the second to last part looked like it was being multiplied by the x in the last part
