|4x|-11=9

∣ 4 x ∣ - 11 = 9

x = - 5 or x = 5

Solution steps

∣ 4 x ∣ - 11 = 9

Move

11

to the right side

∣ 4 x ∣ = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x = - 20 or 4 x = 20

4 x = - 20 or 4 x = 20

x = - 5 or x = 5

\frac{5}{- 3} - \frac{- 2}{7}

\frac{z}{- 2} - 6 \leq - 2

3 (2 x + 4) = 2 (2 + 2 x)

1 1^{2} = 7^{2} + x^{2}

4 x^{2} - 11 x - 3 = 0
