I am having trouble understanding the problem and setting up the equation.
Q:
The sum of two integers is eleven. One less than twice the larger number is five times the smaller number. What is the larger number?

I know they want to larger number.
I don't understand the 2nd sent. :roll:

I keep coming up with

11= (two integers)
L=large number S=small number
2L-1=5S
 
Hello, sw87!

Evidently, you don't understand the first sentence.

11 = (two integers) .
How do you write this "in Algebra"?

L = large number, S = small number

2L - 1 = 5S

\(\displaystyle \text{We have: }\;\begin{array}{c}L + S \:=\;11 \\ 2L - 1 \:=\:5S\end{array}\)


\(\displaystyle \text{Solve the system: }\:\begin{Bmatrix}L + S &=& 11 \\ 2L - 5S &=& 1 \end{Bmatrix}\)

 
Thank you i think i figured it out to be the large number equals 8
