2x - 6 = 18

1 answer

To solve the equation \( 2x - 6 = 18 \), follow these steps:

  1. Add 6 to both sides of the equation:

    \[ 2x - 6 + 6 = 18 + 6 \]

    This simplifies to:

    \[ 2x = 24 \]

  2. Now, divide both sides by 2:

    \[ \frac{2x}{2} = \frac{24}{2} \]

    This gives:

    \[ x = 12 \]

So, the solution is \( x = 12 \).
