x - 4 = x

x = \frac{9 + 17}{2}

Decimal Notation

x = 6.56155 \dots

Solution steps

x - 4 = x

Square both sides:

x^{2} - 8 x + 16 = x

x^{2} - 8 x + 16 = x

Solve

x^{2} - 8 x + 16 = x : x = \frac{9 + 17}{2}, x = \frac{9 - 17}{2}

x = \frac{9 + 17}{2}, x = \frac{9 - 17}{2}

Verify Solutions:

x = \frac{9 + 17}{2}

True

, x = \frac{9 - 17}{2}

False

The solution is

x = \frac{9 + 17}{2}

405 = 5 (9 x)^{\frac{4}{3}}

2 x - 3 - x + 7 = 4

x - 3 = 2.35

2 = 14.8 \cdot 1 - n
