r = - 6.5, r = 8

Solution steps

∣ - 3 + 4 r ∣ = 29

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 + 4 r = - 29 or - 3 + 4 r = 29

- 3 + 4 r = - 29 or - 3 + 4 r = 29

r = - \frac{13}{2} or r = 8

e^{x} - x^{2} = 0

∣ 2 y ∣ = 0

8 ∣ 8 - 5 x ∣ = 8 x + 8

8 = 2 ∣ m - 2 ∣

- 2 = - 2 ∣ v ∣
