x-3=sqrt(30-2x)

Solution

x - 3 = 30 - 2 x

Solution

x = 7

Solution steps

x - 3 = 30 - 2 x

Square both sides:

x^{2} - 6 x + 9 = 30 - 2 x

x^{2} - 6 x + 9 = 30 - 2 x

Solve

x^{2} - 6 x + 9 = 30 - 2 x : x = 7, x = - 3

x = 7, x = - 3

Verify Solutions:

x = 7

True

, x = - 3

False

The solution is

x = 7

x - 1 = 10 x - 10

x - 3 = 8 x + 9

sqrt(7+\sqrt{x+1)}=3

7 + x + 1 = 3

x, 1 = x^{0.5} + y^{0.5}

9(sqrt(x))^3-1=2

9 (x)^{3} - 1 = 2
