6x-2(7x+14)=12

6 x - 2 (7 x + 14) = 12

x = - 5

Solution steps

6 x - 2 (7 x + 14) = 12

Expand

- 2 (7 x + 14) : - 14 x - 28

6 x - 14 x - 28 = 12

Add similar elements:

6 x - 14 x = - 8 x

- 8 x - 28 = 12

Move

28

to the right side

- 8 x = 40

Divide both sides by

- 8

x = - 5

- 3 w + 7 = - 9 w + 49

7 + 3 k - 2 = 4 k

x, 3 x - \frac{y - 3}{5} = 6

\frac{x - 2}{4} + \frac{2 x - 6}{5} = \frac{3 - x}{2}

y, y x^{2} - 4 = x
