sqrt(7x+18)=x+4

7 x + 18 = x + 4

x = 1, x = - 2

Solution steps

7 x + 18 = x + 4

Square both sides:

7 x + 18 = x^{2} + 8 x + 16

7 x + 18 = x^{2} + 8 x + 16

Solve

7 x + 18 = x^{2} + 8 x + 16 : x = 1, x = - 2

x = 1, x = - 2

Verify Solutions:

x = 1

True

, x = - 2

True

The solutions are

x = 1, x = - 2

x^{\frac{2}{3}} - 2 x^{\frac{1}{3}} - 15 = 0

3 - x = x - 3

y, x^{\frac{2}{3}} + y^{\frac{2}{3}} = 4

(x) = - 1

8 x + 9 = x
