6×+2=21

1 answer

To solve the equation \( 6x + 2 = 21 \), follow these steps:

  1. Subtract 2 from both sides:

    \[ 6x + 2 - 2 = 21 - 2 \]

    This simplifies to:

    \[ 6x = 19 \]

  2. Now, divide both sides by 6:

    \[ x = \frac{19}{6} \]

So, the solution is:

\[ x = \frac{19}{6} \approx 3.17 \]
