2sqrt(21-x)-sqrt(3x-6)=5

2 21 - x - 3 x - 6 = 5

x = 5

Solution steps

2 21 - x - 3 x - 6 = 5

Remove square roots

49 x^{2} - 910 x + 4225 = 300 x - 600

Solve

49 x^{2} - 910 x + 4225 = 300 x - 600 : x = \frac{965}{49}, x = 5

x = \frac{965}{49}, x = 5

Verify Solutions:

x = \frac{965}{49}

False

, x = 5

True

The solution is

x = 5

x^{2} + 19 = x + 1

- 8 + \frac{m}{6} = - 4

4 \cdot x^{2} + 1 = 0

43 = x - 7
