-5|6a+21|=-15

- 5 ∣ 6 a + 21 ∣ = - 15

a = - 4 or a = - 3

Solution steps

- 5 ∣ 6 a + 21 ∣ = - 15

Divide both sides by

- 5

∣ 6 a + 21 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

6 a + 21 = - 3 or 6 a + 21 = 3

6 a + 21 = - 3 or 6 a + 21 = 3

a = - 4 or a = - 3

∣ 7 y - 3 ∣ + 1 = 0

∣ 3 x - 8 ∣ = x

∣ - 7 + 4 y ∣ = 17

∣ x ∣ = ∣ y ∣

- 2 + ∣ - 9 n ∣ = 52
