x-2(3x-1)=7

x - 2 (3 x - 1) = 7

x = - 1

Solution steps

x - 2 (3 x - 1) = 7

Expand

- 2 (3 x - 1) : - 6 x + 2

x - 6 x + 2 = 7

Add similar elements:

x - 6 x = - 5 x

- 5 x + 2 = 7

Move

2

to the right side

- 5 x = 5

Divide both sides by

- 5

x = - 1

X^{4} - 12 X^{2} + 32 \leq 0

5 x^{2} + 3 = 3

\frac{x - 2}{14} = \frac{2}{7}

x = 2 x e^{4} - e^{4} - 2

\frac{9 !}{( 9 - 4 ) ! \cdot 4 !}
