sqrt(-2x+30)=x-3

Solution

- 2 x + 30 = x - 3

Solution

x = 7

Solution steps

- 2 x + 30 = x - 3

Square both sides:

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

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

Solve

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

x = 7, x = - 3

Verify Solutions:

x = 7

True

, x = - 3

False

The solution is

x = 7
