-2|h-7|=-28

- 2 ∣ h - 7 ∣ = - 28

h = - 7 or h = 21

Solution steps

- 2 ∣ h - 7 ∣ = - 28

Divide both sides by

- 2

∣ h - 7 ∣ = 14

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

h - 7 = - 14 or h - 7 = 14

h - 7 = - 14 or h - 7 = 14

h = - 7 or h = 21

\frac{1}{x - 3} + \frac{1}{x + 2} \geq \frac{2 x}{x ^{2} + x - 2}

x^{3} - x^{2} - 14 x + 24

4 h + 36 = - 20

10 - x \leq 35

3 a^{2} - 48
