----------
Replace the x by 9 then by 10 then by 11 to see which
number makes the equation true.
10 is the answer.

Plug in x=9

Combine like terms. Since the equation is not true, x=9 is not a solution

--------------------------------------------------------------------------------

Plug in x=10

Combine like terms. Since the equation is true, x=10 is a solution

--------------------------------------------------------------------------------

Plug in x=11

Combine like terms. Since the equation is not true, x=11 is not a solution

--------------------------------------------------------------------------------

Answer:

So the only solution is x=10
