Question 1039692
{{{system(h=howmanyPintsperCup,k=howmanyPintsperLiter)}}}



Abbreviated units here will be c for cups, L for liters, p for pints.  These are not being used as variables, but as UNITS of volume.
{{{system(7c+3L=9.8p,5L-9c=6p)}}}



Might be more than one way to go.  Try changing Melissa's equation to all pints; and Emily's equation to all pints.


{{{system(7h+3k=9.8,5k-9h=6)}}}
or keeping form the same,
{{{system(7h+3k=9.8,-9h+8.5k=6)}}}
That is the system.  Two linear equations in two unknown unit conversion ratios.
