2+|5n|=17

2 + ∣ 5 n ∣ = 17

n = - 3 or n = 3

Solution steps

2 + ∣ 5 n ∣ = 17

Move

2

to the right side

∣ 5 n ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 n = - 15 or 5 n = 15

5 n = - 15 or 5 n = 15

n = - 3 or n = 3

lo g_{10} (x) + lo g_{10} (x - 3) = 1

x^{2} + 18 x y + 81 y^{2}

x (4 x - 9) = 0

\frac{4}{5} \cdot \frac{3}{5}

x - x^{2} - 1 \leq 0
