2|4x|=40

2 ∣ 4 x ∣ = 40

x = - 5 or x = 5

Solution steps

2 ∣ 4 x ∣ = 40

Divide both sides by

2

∣ 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

x^{3} y^{3} + 216

- 2 (5) + 3 y - 4 = 0

\frac{14}{25} = v + \frac{1}{2}

- 1.3 \geq 2.9 - 0.6 r

n^{2} - 120 = 7 n
