3 ∣ 3 - 5 r ∣ - 3 = 18

r = - \frac{4}{5} or r = 2

Decimal Notation

r = - 0.8, r = 2

Solution steps

3 ∣ 3 - 5 r ∣ - 3 = 18

Move

3

to the right side

3 ∣ 3 - 5 r ∣ = 21

Divide both sides by

3

∣ 3 - 5 r ∣ = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 - 5 r = - 7 or 3 - 5 r = 7

3 - 5 r = - 7 or 3 - 5 r = 7

r = - \frac{4}{5} or r = 2

3 x + 2 > - 4 and 2 x - 1 \leq 5

7 x^{3} + 4 x^{5}

x^{2} + 6 x + 19 < 10

30.29 = - 1.705 x + 98.488

- \frac{1}{- 1}
