Let's use the variable "J" to represent the number of posters Jess did, and "G" to represent the number of posters Gabby did.
If they made 20 posters together, we have:
[tex]J+G=20[/tex]Then, if Jess made 5 posters (that is, J = 5), we can calculate how many posters Gabby did:
[tex]\begin{gathered} 5+G=20 \\ G=20-5 \\ G=15 \end{gathered}[/tex]So Gabby did 15 posters.
