let 'x' be the amount of pork
     'y' be the amount of beef 
x + y = 7   ----equation 1
knowing the ratio as 3:1 ( beef:pork)
we can say that if in every 3x of beef there's x amount of pork
then we'll have y=3x  ---equation 2
substitute equation 2 to equation 1
x + y = 7
x + 3x = 7
4x = 7
x = 7/4 pounds of pork
