sqrt(9x+63)=x+7

9 x + 63 = x + 7

x = 2, x = - 7

Solution steps

9 x + 63 = x + 7

Square both sides:

9 x + 63 = x^{2} + 14 x + 49

9 x + 63 = x^{2} + 14 x + 49

Solve

9 x + 63 = x^{2} + 14 x + 49 : x = 2, x = - 7

x = 2, x = - 7

Verify Solutions:

x = 2

True

, x = - 7

True

The solutions are

x = 2, x = - 7

\frac{5 x - 8}{3 x ^{\frac{1}{3}}} = 0

2 x + 7 - 2 = x

3 x - 5 + x - 2 = 3

2 x - 5 + x + 6 = 4

y, x^{2} + y^{2} = 1
