x-3x=2(4+x)

x - 3 x = 2 (4 + x)

x = - 2

Solution steps

x - 3 x = 2 (4 + x)

Add similar elements:

x - 3 x = - 2 x

- 2 x = 2 (4 + x)

Expand

2 (4 + x) : 8 + 2 x

- 2 x = 8 + 2 x

Move

2 x

to the left side

- 4 x = 8

Divide both sides by

- 4

x = - 2

2 x - 5 = 1 - 2 x

3 x - 5 x - (3 x + 5 x) = 2 x - 8 x

13.1 = x - 4

3 (4 + x) = 5 (x + 4) + 1 - 3 x

\frac{p}{6} + \frac{2}{3} = 1
