sqrt(5-5x)=x+9

Solution

5 - 5 x = x + 9

Solution

x = - 4

Solution steps

5 - 5 x = x + 9

Square both sides:

5 - 5 x = x^{2} + 18 x + 81

5 - 5 x = x^{2} + 18 x + 81

Solve

5 - 5 x = x^{2} + 18 x + 81 : x = - 4, x = - 19

x = - 4, x = - 19

Verify Solutions:

x = - 4

True

, x = - 19

False

The solution is

x = - 4
