Question 20837
5x-4x+3=9-x
first I would subtract 5x-4x giving me x+3=9-x then I would add x to both sides of the problem giving me x+x+3=9-x+x which becomes 2x+3=9 then I would subtract 3 from both sides which becomes 2x+3-3=9-3 or 2x=6 then I would write the problem as follows 2/2x = 6/2 solving it x=3
