8-3x = 128 -3x = 128-8 -3x = 120 x = -40
3x+4=10 To solve: 3x+4=10 3x=6 x=2
3 ln(x) = ln(3x)ln(x3) = ln(3x)x3 = 3xx2 = 3x = sqrt(3)x = 1.732 (rounded)
x + 2x = 33 3x = 33 3x/3 = 33/3 x = 11
3x-2 = 2x+3 3x-2x = 3+2 x = 5
3x=24 x=8
3x-11 for x=9
3x=96-75 3x=21 x=7
3x=12 3x/3=12/3 x=4
x = -3
x = -8
x=4 x=4
x - 7 - 9 = -3x - 16 = -3x = 13
g (x) = -3x+5 -3x= 5 x= -5/3
3x+6 = x-10 3x-x = -10-6 2x = -16 x = -8
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
