Respuesta :

Given:

[tex]y=2x+2[/tex][tex]y=x+6[/tex]

Required:

We need to find the value of x when both equations are equal.

Explanation:

Equate the right side of the equations.

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

Substract x from both sides of the equations.

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

Substract 2 from both sides of the equations.

[tex]x+2-2=6-2[/tex][tex]x=4[/tex]

Final answer:

4 movies.
