-1.8 =x

Step-by-step explanation:

12(x+3)=-8x

Distribute

12x +36 = -8x

Subtract 12x from each side

12x-12x +36 = -8x-12x

36 = -20x

Divide each side by -20

36/-20 = -20x/-20

-9/5 = x

Changing to decimal form

-1.8 =x

c. -1.8

Step-by-step explanation:

12(x+3) = -8x

12x + 36 = -8x

20x = -36

x = -36/20

x = -1.8
