3x-7x-12=2x-6

3 x - 7 x - 12 = 2 x - 6

x = - 1

Solution steps

3 x - 7 x - 12 = 2 x - 6

Add similar elements:

3 x - 7 x = - 4 x

- 4 x - 12 = 2 x - 6

Move

12

to the right side

- 4 x = 2 x + 6

Move

2 x

to the left side

- 6 x = 6

Divide both sides by

- 6

x = - 1

x, 8 x - 4 y = 0

4 (2 x - 1) = 4 + 8 (x - 1)

\frac{x - 1}{7} + \frac{2 - x}{14} = 2 - \frac{x + 2}{4}

8 x = 5

\frac{n}{4} = 13
