Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

[tex]3x + 2 = x + 4(x+2)[/tex]

Expand the brackets.

[tex]3x + 2 = x + 4x+8[/tex]

[tex]3x + 2 = 5x+8[/tex]

Subtract [tex]-5x[/tex] and [tex]-2[/tex] from both sides of the equation.

[tex]3x-5x=8-2[/tex]

[tex]-2x=6[/tex]

[tex]\frac{-2x}{-2}=\frac{6}{-2}[/tex]

Divide [tex]-2[/tex] on both sides of the equation.

[tex]x=-3[/tex]
