- 4.2 \leq x \leq 1

Solution steps

- 25 \leq 5 x - 4 \leq 1

a \leq u \leq b

then

a \leq u and u \leq b

- 25 \leq 5 x - 4 and 5 x - 4 \leq 1

- 25 \leq 5 x - 4 : x \geq - \frac{21}{5}

5 x - 4 \leq 1 : x \leq 1

Combine the intervals

x \geq - \frac{21}{5} and x \leq 1

3 (x + 2) - 6 > - 2 (x - 3) + 14

x^{2} - 5 x - 4 = 0

\frac{p}{9} - 1 \leq - 2

3 (x - 2) - 4 x \geq - 2

m^{2} - 16 = 0
