-1-3u+11u=-14+9u

- 1 - 3 u + 11 u = - 14 + 9 u

u = 13

Solution steps

- 1 - 3 u + 11 u = - 14 + 9 u

Add similar elements:

- 3 u + 11 u = 8 u

- 1 + 8 u = - 14 + 9 u

Move

1

to the right side

8 u = 9 u - 13

Move

9 u

to the left side

- u = - 13

Divide both sides by

- 1

u = 13

x, 2 x - 3 y + 7 = 0

(x - 5)^{2} = x (x - 8) + 11

- 9 T - 21 = 24

x, \frac{x}{2} - \frac{y}{3} = 1

4 + \frac{k}{2} = - 3
