What does x equals in 3x 12 equals 18?
3x+12 = 18 3x = 18-12 3x = 6 x = 2
What is 3x y equals 4 and x y equals 0?
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
If 3x-2 equals 19 then what is the value of x?
3x - 2 = 19Add 2 to each side:3x = 21Divide each side by 3:x = 7
X minus 3X minus 6 divided 6 equals 3X plus 2 divided by 3?
(x - 3x - 6) / 6 = (3x + 2) / 2 ∴2(3x + 2) = 6(3x + 2) ∴6x + 4 = 18x = 12 ∴12x = -8 ∴x = -2/3
