Answer:

Eleven less than twice a number is nine

Let x represent the number.

2x - 11 = 92x−11=9

Find the number :

\begin{gathered}2x - 11 = 9 \\ \\ 2x = 9 + 11 \\ \\ 2x = 20 \\ \\ \frac{2x}{2} = \frac{20}{2} \\ \\ x = 10 \end{gathered}

2x−11=9

2x=9+11

2x=20

2

2x

=

2

20

x=10

Check to verify :

\begin{gathered}2(10) - 11 = 9 \\ \\ 20 - 11 = 9 \\ \\ 9 = 9\end{gathered}

2(10)−11=9

20−11=9

9=9
