3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
x = 6
3x+4 = 2x-3 3x-2x = -3-4 x = -7
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
3x+4=10 To solve: 3x+4=10 3x=6 x=2
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
172=x
4 + 3x = -8subtract four from each side3x = -12divide each side by threex = -4
4+3x-27=-12 To solve it... 3x= -12-4+27 3x= 11 x= 11/3 x= 3.666
3x-4=5x+6 gives: 2x=-10 which gives x=-5
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
