Answer:

[tex]27[/tex]

Step-by-step explanation:

We start by setting an equation.  We have [tex]2x+x+9=90[/tex] which simplifies to [tex]3x+9=90[/tex].  Subtract [tex]9[/tex] from both sides leaves us to solve for x when [tex]3x=81[/tex] divide by [tex]3[/tex] on both sides, we get [tex]x=27[/tex].
