Question

Gizmos cost $2 to ship and widgets cost $3 to ship. If a company is shipping 50 gizmos and widgets for $122, how many are gizmos and how many are widgets? 

Answer 1

g+w=50

2g+3w=122-------A

using elimination method multiply 2 to the first equation 

2g+2w=100--------B

subtract equation A-B

w=22, then g=28
