sqrt(27-3x)=x+9

Solution

27 - 3 x = x + 9

Solution

x = - 3

Solution steps

27 - 3 x = x + 9

Square both sides:

27 - 3 x = x^{2} + 18 x + 81

27 - 3 x = x^{2} + 18 x + 81

Solve

27 - 3 x = x^{2} + 18 x + 81 : x = - 3, x = - 18

x = - 3, x = - 18

Verify Solutions:

x = - 3

True

, x = - 18

False

The solution is

x = - 3
