5(2-u)-u=2(u+1)

5 (2 - u) - u = 2 (u + 1)

u = 1

Solution steps

5 (2 - u) - u = 2 (u + 1)

Expand

5 (2 - u) : 10 - 5 u

10 - 5 u - u = 2 (u + 1)

Add similar elements:

- 5 u - u = - 6 u

10 - 6 u = 2 (u + 1)

Expand

2 (u + 1) : 2 u + 2

10 - 6 u = 2 u + 2

Move

10

to the right side

- 6 u = 2 u - 8

Move

2 u

to the left side

- 8 u = - 8

Divide both sides by

- 8

u = 1

x^{3} - 3 x^{2} - x + 3 \geq 0

\frac{8}{6} - \frac{5}{4}

6 = \frac{x}{7} - 8

∣ 4 w + 2 ∣ = ∣ 4 w - 5 ∣

2 x^{2} = 150
