sqrt(7x+39)=x+7

7 x + 39 = x + 7

x = - 2, x = - 5

Solution steps

7 x + 39 = x + 7

Square both sides:

7 x + 39 = x^{2} + 14 x + 49

7 x + 39 = x^{2} + 14 x + 49

Solve

7 x + 39 = x^{2} + 14 x + 49 : x = - 2, x = - 5

x = - 2, x = - 5

Verify Solutions:

x = - 2

True

, x = - 5

True

The solutions are

x = - 2, x = - 5

x + 7 - 11 = 2

2 + 2 X = - X + 10

9 y + 4 = 7 y + 1 + 1

2 x^{\frac{7}{2}} - 10 = 0

- 10 x^{\frac{1}{2}} = x + 25
