3 ∣ 9 x ∣ + 4 = 16

x = - \frac{4}{9} or x = \frac{4}{9}

Decimal Notation

x = - 0.44444 \dots, x = 0.44444 \dots

Solution steps

3 ∣ 9 x ∣ + 4 = 16

Move

4

to the right side

3 ∣ 9 x ∣ = 12

Divide both sides by

3

∣ 9 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

9 x = - 4 or 9 x = 4

9 x = - 4 or 9 x = 4

x = - \frac{4}{9} or x = \frac{4}{9}

\frac{2 ( x + 5 )}{3} = 8

- 24 + x = - 3

x^{2} + 10 x + 1 = 0

(b^{2} + 8 b - 9) - (11 b^{2} - 4 b + 7)

4 x^{2} - 1 y^{4} x^{2} - 4 x + 1
