|x+3|=5

∣ x + 3 ∣ = 5

x = - 8 or x = 2

Solution steps

∣ x + 3 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 3 = - 5 or x + 3 = 5

x + 3 = - 5 or x + 3 = 5

x = - 8 or x = 2

- 3 = (x - 2)^{2} - 7

2 x z - 6 x y + 2 yz - 6 y^{2}

m^{2} - 6 m + 9 = 0

\frac{2}{5} + \frac{4}{3}
