x = x - 4

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

Decimal Notation

x = 6.56155 \dots

Solution steps

x = x - 4

Square both sides:

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

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

Solve

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

6 + 6 - 15 x = 15

x - 2 = 3

x + 2 = 1.1 x^{5}

x - 1 = x - 3

56 - x = x
