sqrt(7-3x)=x+7

Solution

7 - 3 x = x + 7

Solution

x = - 3

Solution steps

7 - 3 x = x + 7

Square both sides:

7 - 3 x = x^{2} + 14 x + 49

7 - 3 x = x^{2} + 14 x + 49

Solve

7 - 3 x = x^{2} + 14 x + 49 : x = - 3, x = - 14

x = - 3, x = - 14

Verify Solutions:

x = - 3

True

, x = - 14

False

The solution is

x = - 3
