3x-8=2x+12 3x=2x+20 5x=20 which line did i mess up on? x=4

jimthompson5910 (jim_thompson5910):

you added 2x to both sides when you should have subtracted 2x from both sides

so line 2?

jimthompson5910 (jim_thompson5910):

line 2 to 3, so I would say line 3 mostly

thx!

jimthompson5910 (jim_thompson5910):

instead of 5x = 20, it should be 1x = 20 or x = 20 for line 3
