10x-6(2x+5)=20

10 x - 6 (2 x + 5) = 20

x = - 25

Solution steps

10 x - 6 (2 x + 5) = 20

Expand

- 6 (2 x + 5) : - 12 x - 30

10 x - 12 x - 30 = 20

Add similar elements:

10 x - 12 x = - 2 x

- 2 x - 30 = 20

Move

30

to the right side

- 2 x = 50

Divide both sides by

- 2

x = - 25

x (x - 5) = 0

2 x^{2} - 4 x = 3

\frac{x + 3}{x - 2} < 1

24 3^{\frac{7}{10}} \cdot 24 3^{\frac{1}{10}}
