2 x + x + 1 = 8

x = 3

Solution steps

2 x + x + 1 = 8

Remove square roots

x + 1 = 64 - 32 x + 4 x^{2}

Solve

x + 1 = 64 - 32 x + 4 x^{2} : x = \frac{21}{4}, x = 3

x = \frac{21}{4}, x = 3

Verify Solutions:

x = \frac{21}{4}

False

, x = 3

True

The solution is

x = 3

k, 2 k - 1 - ak = b

0.13 = 0.535 \cdot h^{1.53}

x, 0 = y - x^{2}

6 x + 37 - 15 = - 8

x + 20 - x - 4 = 4
