Let s = Su's pay
Let j = Jen's pay
:
Write an equation for each statement:
:
Sujean says "The sum of your pay and twice mine is $840."
2s + j = 840
:
Jeni says, "The sum of your pay and twice mine is $900."
s + 2j = 900
:
Add the 2 equations together
2s + j = 840
s + 2j = 900
-------------
3s + 3j = 1740
Simplify divide by 3
s + j = $580, they earn together each week
