If x-3x=18 then x equals -9
18 = 3x6 = x
3x-4x=12 that means -x equals 12 so x equals -12
If x equals 8, then 3x equals 24. 24-x would equal 16.
you mean: x+3x+3=x+18 so x=5
If x-3x=18 then x equals -9
3x+12 = 18 3x = 18-12 3x = 6 x = 2
If: 3x+6 = 18 Then: x = 4
The answer is x = 6
18 = 3x6 = x
3x-4x=12 that means -x equals 12 so x equals -12
If x equals 8, then 3x equals 24. 24-x would equal 16.
x^2+3x-18=0 (x+6)(x-3)=0
you mean: x+3x+3=x+18 so x=5
x=2.52
X=18
If 3x - 9 = -6 then 3x must equal 3. Therefore x = 1 !
