3 ∣ 2 x + 5 ∣ + 7 = 25

x = - \frac{11}{2} or x = \frac{1}{2}

Decimal Notation

x = - 5.5, x = 0.5

Solution steps

3 ∣ 2 x + 5 ∣ + 7 = 25

Move

7

to the right side

3 ∣ 2 x + 5 ∣ = 18

Divide both sides by

3

∣ 2 x + 5 ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 5 = - 6 or 2 x + 5 = 6

2 x + 5 = - 6 or 2 x + 5 = 6

x = - \frac{11}{2} or x = \frac{1}{2}

r^{2} - 6 r - 9 s^{2} + 9

\frac{3 y + 5}{2} - \frac{3 y + 2}{5} = \frac{3}{10}

12 y - 4 = 15 y + 8

15 y = 25 y^{2}

(∣ x + 4 ∣^{2} - 25) (x^{2} - 9) \leq 0
