If x-3x=18 then x equals -9

X=18

3x+12=x+48: 3x-x=-12+48 2x=36 x=18

6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6

3x=18 x=18/3 x=6

3x-4x=12 that means -x equals 12 so x equals -12

If: 3x+6 = 18 Then: x = 4

The answer is x = 6

3x=12 3x/3=12/3 x=4

18 = 3x6 = x

3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12

3x-12=12 express the equation in terms of x, 3x=12+12 then, perform the operation 3x=24 x=8 that is now the value of x.

x = 6

x^2+3x-18=0 (x+6)(x-3)=0

you mean: x+3x+3=x+18 so x=5

3x+8 = 12 3x = 4 x = 4/3

6x - 12 = 3x + 15 3x = 27 x = 9

3x-1 = 11 3x = 11+1 = 12 x = 12/3 = 4 Therefore: x2 + 2 = 16 + 2 = 18

3x + 8 = 20 - 3x 6x = 12 x = 2

2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7

If: 3x+6 = 12 Then: x = 2

3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4

3x - 12 = -2x + 235x = 35 so x = 7
