x =7

Step-by-step explanation:

3x - 9 + 12 - 6x = -18

Combine like terms

-3x +3 = -18

Subtract 3 from each side

-3x +3 -3 = -18 -3

-3x = -21

Divide each side by-3

-3x /-3 = -21 /-3

x =7

x=7

Step-by-step explanation:

3x - 9 + 12 - 6x = -18

3x+ - 9 + 12+ - 6x = -18

3x+- 6x + - 9 + 12+ = -18

-3x+ 3= -18

-3x= -18-3

-3x= -21

3x=21

x=21/3

x=7
