4(3-u)+u=22+2u

4 (3 - u) + u = 22 + 2 u

u = - 2

Solution steps

4 (3 - u) + u = 22 + 2 u

Expand

4 (3 - u) : 12 - 4 u

12 - 4 u + u = 22 + 2 u

Add similar elements:

- 4 u + u = - 3 u

12 - 3 u = 22 + 2 u

Move

12

to the right side

- 3 u = 2 u + 10

Move

2 u

to the left side

- 5 u = 10

Divide both sides by

- 5

u = - 2

y^{2} - 11 y + 30 = 0

- 20 a b^{2} + 185 ab - 315 a

14 - 5 t = 3 t

4 x^{2} + 4 x + 3 = 0

j^{2} = 25
