3x−5

1 answer

To solve the equation \( 7x - 9 = 3x - 5 \), follow these steps:

  1. Isolate the variable terms: First, let's get all \( x \) terms on one side of the equation by subtracting \( 3x \) from both sides:

    \[ 7x - 3x - 9 = -5 \]

    This simplifies to:

    \[ 4x - 9 = -5 \]

  2. Isolate the constant term: Next, add \( 9 \) to both sides to get rid of the constant on the left side:

    \[ 4x - 9 + 9 = -5 + 9 \]

    Simplifying gives:

    \[ 4x = 4 \]

  3. Solve for \( x \): Now divide both sides by \( 4 \):

    \[ x = 1 \]

Thus, the solution to the equation \( 7x - 9 = 3x - 5 \) is \( x = 1 \).
