7-8|-2x-3|=-65

7 - 8 ∣ - 2 x - 3 ∣ = - 65

x = - 6 or x = 3

Solution steps

7 - 8 ∣ - 2 x - 3 ∣ = - 65

Move

7

to the right side

- 8 ∣ - 2 x - 3 ∣ = - 72

Divide both sides by

- 8

∣ - 2 x - 3 ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 2 x - 3 = - 9 or - 2 x - 3 = 9

- 2 x - 3 = - 9 or - 2 x - 3 = 9

x = - 6 or x = 3

2 x - 8 \geq 9 x - 10

p^{2} = 64

2 (1 - x) = - \frac{2}{3}

lo g_{10} (5) + lo g_{10} (2)
