Answer:

x = 3

Add 9 to both sides:

6x - 9 = 3x

6x - 9 + 9 = 3x + 9

Simplify:

6x = 3x + 9

Subtract 3x from both sides:

6x = 3x + 9

6x - 3x = 3x + 9 - 3x

Simplify:

3x = 9

Divide both side by the same factor:

3x = 9

3x/3 = 9/3

Simplify:

x = 3

Step-by-step explanation:

Hope it helps! =D
