Answer:
[tex]x=9[/tex]
Step-by-step explanation:
Assuming you'd like to solve for [tex]x[/tex], start with:
[tex]20(x+1)=200[/tex]
Distribute the [tex]20[/tex] into the [tex](x+1)[/tex]:
[tex]20x+20=200[/tex]
Subtract [tex]20[/tex] from both sides of the equation:
[tex]20x=180[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]20[/tex]:
[tex]x=9[/tex]
