x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
x = -3
6x2=-7
So, we have 3x = 4 for some number x. We will solve for x. 3x = 4 (1/3)*(3x) = (1/3)*(4) [multiplied by (1/3) on both sides] x = 4/3
3x=24 x=8
3x-11 for x=9
3x = (96-75) 3x = 21So X = 7
3x=96-75 3x=21 x=7
3x - 4 = -2 The answer is x=2/3
g (x) = -3x+5 -3x= 5 x= -5/3
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
3x+6 = x-10 3x-x = -10-6 2x = -16 x = -8
You need an equal sign to solve for x.
3x=12 3x/3=12/3 x=4
x - 7 - 9 = -3x - 16 = -3x = 13
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
