3x-11 for x=9
If x-3x=18 then x equals -9
No.

3x-y=9 y=3x-9
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
the answer is -3x = 0
3x-11 for x=9
If x-3x=18 then x equals -9
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
No.
3x-3 = 6 3x = 6+3 3x = 9 x = 3
3x - 2 = 9 3x = 9 + 2 = 11 x = 11/3
(3x - 9 =15) +9 = 3x=(24)/3 = x=8 x=8
-3x=-15+6 -3x=-9 x=-9/-3 x=3
