x + 9 + x = 3

x = \frac{19 - 73}{2}

Decimal Notation

x = 5.22799 \dots

Solution steps

x + 9 + x = 3

Remove square roots

x + 9 = 81 - 18 x + x^{2}

Solve

x + 9 = 81 - 18 x + x^{2} : x = \frac{19 + 73}{2}, x = \frac{19 - 73}{2}

x = \frac{19 + 73}{2}, x = \frac{19 - 73}{2}

Verify Solutions:

x = \frac{19 + 73}{2}

False

, x = \frac{19 - 73}{2}

True

The solution is

x = \frac{19 - 73}{2}

x - 10 = - 2

3 x^{2} - 2 = 2 x - 1

x + 3 = 3 x - 1

5 x - 6 - x = 0

x, x + x y + y = 1
