|-2x|=4

∣ - 2 x ∣ = 4

x = - 2 or x = 2

Solution steps

∣ - 2 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 2 x = - 4 or - 2 x = 4

- 2 x = - 4 or - 2 x = 4

x = - 2 or x = 2

\frac{x ^{2}}{x ^{- 2}}

5 x - 12 = 2 x + 24

\frac{1}{8} + c = \frac{4}{5}

(- 2 x^{5} y^{7})^{3} + 7 x^{15} y^{21}

- 3 x^{2} + 75 = 0
