3*3 - 5 = 9-5 = 4 4*3 = 12 4 ≠ 12 so x=3 is not the solution ... _________________________ 3x - 5 = 4x you need to put the x terms on one side and the rest on the other side (be careful about the sign + or - that change when you change the place of a term) 3x - 4x = 5 -x = 5 x = -5

Yes 3x-5=4x is is exactly what it is like on the paper
