x = 5 - x

x = \frac{- 1 + 21}{2}

Decimal Notation

x = 1.79128 \dots

Solution steps

x = 5 - x

Square both sides:

x^{2} = 5 - x

x^{2} = 5 - x

Solve

x^{2} = 5 - x : x = \frac{- 1 + 21}{2}, x = \frac{- 1 - 21}{2}

x = \frac{- 1 + 21}{2}, x = \frac{- 1 - 21}{2}

Verify Solutions:

x = \frac{- 1 + 21}{2}

True

, x = \frac{- 1 - 21}{2}

False

The solution is

x = \frac{- 1 + 21}{2}

u = - 3 u + 10

x - 8 + x = 4

x + 22 + x + 6 = 8

x^{(\frac{1}{3})} = 2

2 x^{2} - 2 = 4
