Move

2

to the right side

∣ 2 t + 5 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 t + 5 = - 3 or 2 t + 5 = 3

2 t + 5 = - 3 or 2 t + 5 = 3

t = - 4 or t = - 1

16 - 4 x^{2} + 12 x y - 9 y^{2}

(64 x^{4})^{\frac{1}{2}}

1 + x < 7 x + 5

x \cdot x^{- \frac{1}{3}}

6 x^{2} + 5 x = 21
