Solve 5x - 7 = 3x + 9

5 x - 7 = 3 x + 9

Step by step

  1. 5 x - 7 = 3 x + 9

    Start from the equation as given.

  2. 2 x - 16 = 0

    Bring everything to one side and collect like terms so the right-hand side is 0.

  3. 2 x = 16

    Move the constant term to the other side: subtract -16 from both sides.

  4. x = \frac{16}{2}

    Divide both sides by 2, the coefficient of x.

  5. x = 8

    Simplify the fraction.

x = 8
