sqrt(x-7)-sqrt(2x-7)=-2

x - 7 - 2 x - 7 = - 2

x = 16, x = 8

Solution steps

x - 7 - 2 x - 7 = - 2

Remove square roots

x^{2} + 8 x + 16 = 32 x - 112

Solve

x^{2} + 8 x + 16 = 32 x - 112 : x = 16, x = 8

x = 16, x = 8

Verify Solutions:

x = 16

True

, x = 8

True

The solutions are

x = 16, x = 8

10 - x + x + 3 = 5

3 - 2 x = x + 6

(1 - x)^{2} = 1 - x

x^{2} + 8 x + x^{2} + 8 x = 12

x^{3} - x^{\frac{1}{3}} = 0
