x = - 0.4, x = 0.4

Solution steps

7 ∣ 5 x ∣ + 2 = 16

Move

2

to the right side

7 ∣ 5 x ∣ = 14

7

∣ 5 x ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x = - 2 or 5 x = 2

5 x = - 2 or 5 x = 2

x = - \frac{2}{5} or x = \frac{2}{5}

a^{2} + ab + a c + b c

(5 b) (- 3 a)

6 x^{2} + 3 x y - 2 a x - a y

(\frac{1}{2}) (\frac{1}{130}) (\frac{60}{1})

- 4 x^{2} + 16 x = 21
