sqrt(2x+8)-sqrt(x+11)=-1

2 x + 8 - x + 11 = - 1

x = - 2

Solution steps

2 x + 8 - x + 11 = - 1

Remove square roots

x^{2} - 8 x + 16 = 4 x + 44

Solve

x^{2} - 8 x + 16 = 4 x + 44 : x = 14, x = - 2

x = 14, x = - 2

Verify Solutions:

x = 14

False

, x = - 2

True

The solution is

x = - 2

5 - x + x + 3 = 0

x, y 5 - 2 x - 3 = 0

8 - 2 x - x = 0

- x = 2 - (10 x - 5)

3 x + 4 - 2 = 2 x - 4
