Question

Ayudenme con este problema!!!!!!!

Answer 1

a)

$11 < 2x - 5 < 29 \\ 11 + 5 < 2x < 29 + 5 \\ 16 < 2x < 34 \\ \frac{16}{2} < x < \frac{34}{2} \\ 8 < x < 17$

b)

$- 12 < 3x + 6 < 18 \\ - 12 - 6 < 3x < 18 - 6 \\ - 18 < 3x < 12 \\ \frac{ - 18}{3} < x < \frac{12}{3} \\ - 6 < x < 4$

c)

$- 15 < 4x - 3 < 21 \\ - 15 + 3 < 4x < 21 + 3 \\ - 12 < 4x < 24 \\ \frac{ - 12}{4} < x < \frac{24}{4} \\ - 3 < x < 6$

d)

$- 36 < 5x + 4 < 24 \\ - 36 - 4 < 5x < 24 - 4 \\ - 40 < 5x < 20 \\ \frac{ - 40}{5} < x < \frac{20}{5} \\ - 8 < x < 4$
