|y|-8=-5

∣ y ∣ - 8 = - 5

y = - 3 or y = 3

Solution steps

∣ y ∣ - 8 = - 5

Move

8

to the right side

∣ y ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

y = - 3 or y = 3

x + 4 (3.5 x) = 15

(1 6^{\frac{3}{4}})^{2}

2 \cdot \frac{1}{2}

8 - \frac{2 - 2 x}{4} = 5 x

- 4 (- 2) + 5 (- 5) = 6
