sqrt(10x+69)=x+9

10 x + 69 = x + 9

x = - 2, x = - 6

Solution steps

10 x + 69 = x + 9

Square both sides:

10 x + 69 = x^{2} + 18 x + 81

10 x + 69 = x^{2} + 18 x + 81

Solve

10 x + 69 = x^{2} + 18 x + 81 : x = - 2, x = - 6

x = - 2, x = - 6

Verify Solutions:

x = - 2

True

, x = - 6

True

The solutions are

x = - 2, x = - 6

7 x + 15 = x + 1

2 y + 2 = \frac{2 ( y + 2 )}{3}

3 x + 10 + 1 = 6 - 3 x + 3

x^{2} - 63 = 1
