2^{2} + 3 = ∣ 4 z + 5 ∣

z = - 3 or z = \frac{1}{2}

Solution steps

2^{2} + 3 = ∣ 4 z + 5 ∣

Switch sides

∣ 4 z + 5 ∣ = 2^{2} + 3

Simplify

2^{2} + 3 : 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 z + 5 = - 7 or 4 z + 5 = 7

4 z + 5 = - 7 or 4 z + 5 = 7

z = - 3 or z = \frac{1}{2}

∣ z + 2 ∣ = 2

- 3 ∣ 8 - x ∣ = - 11

∣ 1 k - 74 ∣ = 21

5 ∣ 2 x - 7 ∣ - 22 = 3

∣ 2 - 4 t ∣ + 2 = 12
