Solve 2s = 4

2 s = 4

Step by step

  1. 2 s = 4

    Start from the equation as given.

  2. 2 s - 4 = 0

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

  3. 2 s = 4

    Move the constant term to the other side: subtract -4 from both sides.

  4. s = \frac{4}{2}

    Divide both sides by 2, the coefficient of s.

  5. s = 2

    Simplify the fraction.

s = 2
