Solution steps

3 k + 5 + 1 = 3 k

Remove square roots

3 k + 5 = 9 k^{2} - 6 k + 1

Solve

3 k + 5 = 9 k^{2} - 6 k + 1 : k = \frac{4}{3}, k = - \frac{1}{3}

k = \frac{4}{3}, k = - \frac{1}{3}

Verify Solutions:

k = \frac{4}{3}

True

, k = - \frac{1}{3}

False

The solution is

k = \frac{4}{3}

6 d - 11 + 8 = 11
