2*|x+1|=10

2 \cdot ∣ x + 1 ∣ = 10

x = - 6 or x = 4

Solution steps

2 ∣ x + 1 ∣ = 10

Divide both sides by

2

∣ x + 1 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 1 = - 5 or x + 1 = 5

x + 1 = - 5 or x + 1 = 5

x = - 6 or x = 4

3 y^{2} = - y + 2

x^{3} - 4 x^{2} + 25 x - 100

\frac{2}{5} + 1

6 x^{2} - 25 x - 25 = 0

\frac{1}{2} - \frac{1}{1}
