x+2(3x+1)=3(x-2)

x + 2 (3 x + 1) = 3 (x - 2)

x = - 2

Solution steps

x + 2 (3 x + 1) = 3 (x - 2)

Expand

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

x + 6 x + 2 = 3 (x - 2)

Add similar elements:

x + 6 x = 7 x

7 x + 2 = 3 (x - 2)

Expand

3 (x - 2) : 3 x - 6

7 x + 2 = 3 x - 6

Move

2

to the right side

7 x = 3 x - 8

Move

3 x

to the left side

4 x = - 8

Divide both sides by

4

x = - 2

2 x^{2} = - 10

4 - 16

x^{2} + 200 = 0
