So for this we need to convert the word problem into an equation, and it'll look like this: [tex]2(n+11)=3n-22[/tex] (n=number). And from there, we can solve.
Multiply 2 and (n+11) and your equation should look like [tex]2n+22=3n-22[/tex]
Add 22 on each side, and your equation should look like [tex]2n+44=3n[/tex]
Subtract 2n on each side, and your answer should should be [tex]44=n[/tex]
