solvefor x,sqrt(x-3)+2x=42

x, x - 3 + 2 x = 42

x = 19

Solution steps

x - 3 + 2 x = 42

Remove square roots

x - 3 = 1764 - 168 x + 4 x^{2}

Solve

x - 3 = 1764 - 168 x + 4 x^{2} : x = \frac{93}{4}, x = 19

x = \frac{93}{4}, x = 19

Verify Solutions:

x = \frac{93}{4}

False

, x = 19

True

The solution is

x = 19

x + x - 15 = 3

- x^{2} - 2 x - 15 = x + 1

1 - 2 x + x + 8 = 5

8 t + 9 = - 9
