8x−9=

5x+9

1 answer

To solve the equation \( 8x - 9 = 5x + 9 \), follow these steps:

  1. Isolate the variable on one side: Start by getting all terms containing \( x \) on one side and constant terms on the other side.

    \[ 8x - 5x = 9 + 9 \]

    Simplifying both sides gives:

    \[ 3x = 18 \]

  2. Solve for \( x \): Divide both sides by 3.

    \[ x = \frac{18}{3} = 6 \]

So, the solution to the equation \( 8x - 9 = 5x + 9 \) is:

\[ \boxed{6} \]
