Question

Solve for the value of x 3x - 9 + 12 - 6x = -18

Answer 1

Answer:

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

Answer 2

Answer:

$x=7$

Step-by-step explanation:

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

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

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

$-3x+ 3= -18$

$-3x= -18-3$

$-3x= -21$

$3x=21$

$x=21/3$

$x=7$
