Define the variables and write a system of equations to represent the situation?

 

 

I thought 5s+7a=1,11o

 

 

Use  ROW REDUCTION or INVERSE MARTICES to solve?   HELPsad

We don't have enough info to solve this......your equation is correct, but s and a may - or may not - have integer solutons with just one equation..........we need to generate another equation  involving s and a, somehow

 

 

cool cool cool
