sqrt(65-7x)=x-5

Solution

65 - 7 x = x - 5

Solution

x = 8

Solution steps

65 - 7 x = x - 5

Square both sides:

65 - 7 x = x^{2} - 10 x + 25

65 - 7 x = x^{2} - 10 x + 25

Solve

65 - 7 x = x^{2} - 10 x + 25 : x = 8, x = - 5

x = 8, x = - 5

Verify Solutions:

x = 8

True

, x = - 5

False

The solution is

x = 8
