Answer:

x = 1

Step-by-step explanation:

9 + 3x = 18 - 6x

3x + 6x = 18 - 9

9x = 9

X = 1

Answer:

Step-by-step explanation:

9+3x =6(3-x)

9+3x =6 ×3 - 6x

9+3x =18 -6x

Collect like terms

9-18= -6x-3x

-9 =-9x

Divide both sides by -9

-9/-9 =-9x/-9

Minus cancels minus and 9 divided by 9 is 1 on both sides

1 =x

x =1
