9(j-2)=P-- this says that 9 times jars minus 2 equals pencils
P-7j=3 --this says that pencils minus seven jars equals 3 leftover pencil
Expand the first equation:
9j-18=P
Plug that into the second one:
9j-18-7j=3
simplify
2j-18=3
add 18:
2j=21
j=21/2
j=10.5
use equation for P
9j-18=p
9*10.5-18=P
P=76.5
