7|2a-5|-15=20

7 ∣ 2 a - 5 ∣ - 15 = 20

a = 0 or a = 5

Solution steps

7 ∣ 2 a - 5 ∣ - 15 = 20

Move

15

to the right side

7 ∣ 2 a - 5 ∣ = 35

Divide both sides by

7

∣ 2 a - 5 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 a - 5 = - 5 or 2 a - 5 = 5

2 a - 5 = - 5 or 2 a - 5 = 5

a = 0 or a = 5

∣ y + 840 ∣ = 40

∣ 2 (x - 3) (x + 5) ∣ = 2

5 - ∣ 4 - x ∣ = - 2

x^{2} - 1 = x + 1

∣ w - 40 ∣ = - 100
