To solve the equation \( 6x - 9 = 3x \), follow these steps:
-
Subtract \( 3x \) from both sides of the equation:
\[ 6x - 3x - 9 = 3x - 3x \]
This simplifies to:
\[ 3x - 9 = 0 \]
-
Next, add 9 to both sides:
\[ 3x - 9 + 9 = 0 + 9 \]
This simplifies to:
\[ 3x = 9 \]
-
Finally, divide both sides by 3:
\[ x = \frac{9}{3} \]
This simplifies to:
\[ x = 3 \]
So, the solution to the equation \( 6x - 9 = 3x \) is \( x = 3 \).
