Question

marco and jess fold 60 napkins altogether. jess folds 20 more than marco. how many napkins do they each fold?

Answer 1

i think 80 i add it together

Answer 2

Marco folds 20 Jess folds 40

Explanation:

m=napkins marco folds and j= napkins jess folds

Set up a system of equations

60=m+j

m+20=j

Solve for one variable then substitute it back into equation to solve for its value

m=60-j

(60-j) +20= j

2j=80

j=40

Substitute j to find m

60=40+m

m= 20
