7|2a+4|+7=105

7 ∣ 2 a + 4 ∣ + 7 = 105

a = - 9 or a = 5

Solution steps

7 ∣ 2 a + 4 ∣ + 7 = 105

Move

7

to the right side

7 ∣ 2 a + 4 ∣ = 98

Divide both sides by

7

∣ 2 a + 4 ∣ = 14

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 a + 4 = - 14 or 2 a + 4 = 14

2 a + 4 = - 14 or 2 a + 4 = 14

a = - 9 or a = 5

16 - x^{2} = 0

- 6 ∣ r + 3 ∣ = - 24

5 = ∣ d - 4 ∣

∣ g + 2 ∣ = 16

∣ 6 x + 18 ∣ = 30
