x = - \frac{1}{4} or x = \frac{9}{4}

Decimal Notation

x = - 0.25, x = 2.25

Solution steps

3 ∣ 4 x - 4 ∣ - 7 = 8

Move

7

to the right side

3 ∣ 4 x - 4 ∣ = 15

Divide both sides by

3

∣ 4 x - 4 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x - 4 = - 5 or 4 x - 4 = 5

4 x - 4 = - 5 or 4 x - 4 = 5

x = - \frac{1}{4} or x = \frac{9}{4}

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

- 4 k + 3.6 = 7.8
