-6
3x-y=9 y=3x-9
the answer is -3x = 0
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x-11 for x=9
If x-3x=18 then x equals -9
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
3x-3 = 6 3x = 6+3 3x = 9 x = 3
(3x - 9 =15) +9 = 3x=(24)/3 = x=8 x=8
-3x=-15+6 -3x=-9 x=-9/-3 x=3
-3x = 9x = 9/(-3)x = -3
7x5=3x-9 35=3x-9 35+9=3x 44=3x 44/3=x 14.3=x x=14.3
3x - 7 = 2 3x = 9 x = 3
