3x-6(5x+5)=9x+6

3 x - 6 (5 x + 5) = 9 x + 6

x = - 1

Solution steps

3 x - 6 (5 x + 5) = 9 x + 6

Expand

- 6 (5 x + 5) : - 30 x - 30

3 x - 30 x - 30 = 9 x + 6

Add similar elements:

3 x - 30 x = - 27 x

- 27 x - 30 = 9 x + 6

Move

30

to the right side

- 27 x = 9 x + 36

Move

9 x

to the left side

- 36 x = 36

Divide both sides by

- 36

x = - 1

(x - 1)^{3} + 8 - x^{3} + 3 x (x + 2) = 17

x + 1 = \frac{21}{2}

x, \frac{( d ^{3} \cdot x )}{( d \cdot t ^{3} )} - x = 0

\frac{2 ( 3 x - 1 ) + 7}{2} = 5 x - 2 (2 x - 7)

- 2 x^{2} = (5 - x) (2 x - \frac{2}{5})
