3 x = 16 - x^{2}

x = \frac{2 2}{5}

Decimal Notation

x = 1.26491 \dots

Solution steps

3 x = 16 - x^{2}

Square both sides:

9 x^{2} = 16 - x^{2}

9 x^{2} = 16 - x^{2}

Solve

9 x^{2} = 16 - x^{2} : x = \frac{2 2}{5}, x = - \frac{2 2}{5}

x = \frac{2 2}{5}, x = - \frac{2 2}{5}

Verify Solutions:

x = \frac{2 2}{5}

True

, x = - \frac{2 2}{5}

False

The solution is

x = \frac{2 2}{5}

3 - x = 2 x - 3

3 x + 7 = 0

3 x - 5 + 3 x + 3 + 1 = 0

(0.3 x)^{2} + x^{2} = 30

x^{9} = x^{3}
