x+x>sqrt((-1)/(21))

x + x > \frac{- 1}{21}

x > i \frac{21}{42}

Solution steps

x + x > \frac{- 1}{21}

Add similar elements:

x + x = 2 x

2 x > \frac{- 1}{21}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

2 x > - \frac{1}{21}

Apply radical rule:

- a = - 1 a

- \frac{1}{21} = - 1 \frac{1}{21}

2 x > - 1 \frac{1}{21}

Apply imaginary number rule:

- 1 = i

2 x > i \frac{1}{21}

Divide both sides by

2

x > i \frac{21}{42}

x, (y - 2) (x - 2) > 0

y + 3 \geq 0

\frac{( 4 - 3 x )}{- 5} < - 12

c, x^{3} + 7 x + 9 > 8 x + c

- 6 x - 4 > 20 - 8 x
