(3x - 9 =15) +9 = 3x=(24)/3 = x=8 x=8
-3x=-15+6 -3x=-9 x=-9/-3 x=3
If x-3x=18 then x equals -9
15=30-3x 15-30=3x -15=3x -15/3=x -5=x
8
(3x - 9 =15) +9 = 3x=(24)/3 = x=8 x=8
-3x=-15+6 -3x=-9 x=-9/-3 x=3
6x - 12 = 3x + 15 3x = 27 x = 9
8
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
If x-3x=18 then x equals -9
If: 3x = 15 Then: x = 5
15=30-3x 15-30=3x -15=3x -15/3=x -5=x
8
3x-11 for x=9
If: -3x = 15 Then: x = -5 Because: -3 times -5 = 15
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
