Answer:
\(\boxed{x=20}\)
Step-by-step explanation:
Less than- you had to subtract by the minus sign.
First you had to translate words into an equation.
2x-9=31
Then you solve by equation and add by nine from both sides of equation form.
\(2x-9+9=31+9\)
\(2x=40\)
Next, you divide by two from both sides of equation form.
\(\frac{2x}{2}= \frac{40}{2}\)
\(40/2=20\)
\(40/20=2\)
\(2*20=40\)
\(20*2=40\)
\(x=20\)
