x = 4 - x

x = \frac{- 1 + 17}{2}

Decimal Notation

x = 1.56155 \dots

Solution steps

x = 4 - x

Square both sides:

x^{2} = 4 - x

x^{2} = 4 - x

Solve

x^{2} = 4 - x : x = \frac{- 1 + 17}{2}, x = \frac{- 1 - 17}{2}

x = \frac{- 1 + 17}{2}, x = \frac{- 1 - 17}{2}

Verify Solutions:

x = \frac{- 1 + 17}{2}

True

, x = \frac{- 1 - 17}{2}

False

The solution is

x = \frac{- 1 + 17}{2}

x^{- \frac{1}{2}} = 0
