Let x = the number of pounds of regular sausage produced
0.72x = the number of pounds of pork used to make the x pounds of regular sausage
0.28x = the number of pounds of turkey used to make the x pounds of regular sausage

Let y = the number of pounds of lite sausage produced
0.22y = the number of pounds of pork used to make the y pounds of lite sausage
0.78y = the number of pounds of turkey used to make the y pounds of lite sausage

system%280.72x+%2B+0.22y+=+2000%2C0.28x+%2B+0.78y+=+2000%29

Multiply both equations by 100

system%2872x+%2B+22y+=+200000%2C28x+%2B+78y+=+200000%29

Divide both equations by 2

system%2836x+%2B+11y+=+100000%2C14x+%2B+39y+=+100000%29

To eliminate x, multiply the first equation by 14 and
the second by -36

system%28504x+%2B+154y+=+1400000%2C-504x+-+1404y+=+-3600000%29

Add them term by term

-1250y=-2200000

y=1760

Substituting in 

36x+%2B+11y+=+100000

36x+%2B+11%281760%29+=+100000

36x+%2B+19360+=+100000

36x+=+80640

x=2240

So they should produce 2240 pounds of regular sausage and 1760 pounds of 
lite sausage.
