|x+1|=3

∣ x + 1 ∣ = 3

x = - 4 or x = 2

Solution steps

∣ x + 1 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 1 = - 3 or x + 1 = 3

x + 1 = - 3 or x + 1 = 3

x = - 4 or x = 2

4 (5 x - 2) = 2 (9 x + 3)

- 22 x^{4} y^{3} z^{3} + 11 x^{7} y^{5} z^{2}

\frac{- 4}{- 8 - 12}

- 2 (- 3 x - 1) - 4 x + 3 = 25

\frac{1}{4 i}
