Let
x---------> the number of books that Jessica has
y---------> the number of books that Wesley has
we know that
[tex] x=0 [/tex] --------> equation [tex] 1 [/tex]
[tex] y=x+2 [/tex] --------> equation [tex] 2 [/tex]
Substitute equation [tex] 1 [/tex] in equation [tex] 2 [/tex]
[tex] y=(0)+2 [/tex]
[tex] y=2 [/tex]
therefore
the answer is
Wesley has [tex] 2\ books [/tex]
