x + 4 = x

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

Decimal Notation

x = 2.56155 \dots

Solution steps

x + 4 = x

Square both sides:

x + 4 = x^{2}

x + 4 = x^{2}

Solve

x + 4 = x^{2} : 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 + 4 = 5

a = b + x

4 - x^{2} = 4 - x

4 x + 2 = 2 x + 1
