2 {x + 1} + x = 7

x = 3

Solution steps

2 {x + 1} + x = 7

Remove square roots

4 {x + 1} = 49 - 14 x + x^{2}

Solve

4 {x + 1} = 49 - 14 x + x^{2} : x = 15, x = 3

x = 15, x = 3

Verify Solutions:

x = 15

False

, x = 3

True

The solution is

x = 3

\frac{1}{x} = 2 b

x - 2 = - 4 + x

4 x^{\frac{1}{2}} = 32

- 2 x = 0
