3 ∣ 7 x ∣ + 2 = 17

x = - \frac{5}{7} or x = \frac{5}{7}

Solution steps

3 ∣ 7 x ∣ + 2 = 17

Move

2

to the right side

3 ∣ 7 x ∣ = 15

Divide both sides by

3

∣ 7 x ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 x = - 5 or 7 x = 5

7 x = - 5 or 7 x = 5

x = - \frac{5}{7} or x = \frac{5}{7}

4 x^{2} - y^{2}

\frac{6 - i}{2 + i}

x^{2} + 11 x = 0

5 x^{2} + 6 x - 32 = 0

(2 x + 1) (x - 2) (3 x - 4) \leq 0
