Answer:

$\sf \: j= (−8)/(7)s+ (445)/(7) , \sf \: s= (−7)/(8)j+ (445)/(8)$

Explanation:

$\sf \: Let's solve for j. \\ \sf \: 7j+8s=445 \\ \sf \: Step 1: \: Add \: -8s \: to \: both \: s ides. \\ \sf \: 7j+8s+−8s=445+−8s \\ \sf \: 7j=−8s+445 \\ \sf \: Step \: 2: \: Divide \: both \: sides \: by \:7. \\ \sf (7j)/(7)= (−8s+445)/(7) \\ \sf \: j= (−8)/(7)s+ (445)/(7) \\$
