7 + 4 ∣ 1 - 5 x ∣ = 47

x = - \frac{9}{5} or x = \frac{11}{5}

Decimal Notation

x = - 1.8, x = 2.2

Solution steps

7 + 4 ∣ 1 - 5 x ∣ = 47

Move

7

to the right side

4 ∣ 1 - 5 x ∣ = 40

Divide both sides by

4

∣ 1 - 5 x ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

1 - 5 x = - 10 or 1 - 5 x = 10

1 - 5 x = - 10 or 1 - 5 x = 10

x = - \frac{9}{5} or x = \frac{11}{5}

- 0.7 + \frac{2}{8}

- 4 (5 + w) > 24

- 3 r > 33

3 (3) + y = 10

5 x + 8 - x = 20 + 4 x - 12
