sqrt(56-8x)=x-7

Solution

56 - 8 x = x - 7

Solution

x = 7

Solution steps

56 - 8 x = x - 7

Square both sides:

56 - 8 x = x^{2} - 14 x + 49

56 - 8 x = x^{2} - 14 x + 49

56 - 8 x = x^{2} - 14 x + 49 : x = 7, x = - 1

x = 7, x = - 1

Verify Solutions:

x = 7

True

, x = - 1

False

The solution is

x = 7
