sqrt(2x+7)-sqrt(x+15)=1

2 x + 7 - x + 15 = 1

x = 21

Solution steps

2 x + 7 - x + 15 = 1

Remove square roots

x^{2} - 18 x + 81 = 4 x + 60

Solve

x^{2} - 18 x + 81 = 4 x + 60 : x = 21, x = 1

x = 21, x = 1

Verify Solutions:

x = 21

True

, x = 1

False

The solution is

x = 21

9 x - 2 - 10 - 2 x = 3

x - 2 = 5

16 = 2 x^{\frac{3}{2}}

- 3 + (3 - 2 x)^{\frac{5}{4}} = 29
