Let $\"+a+\"$ = pounds of orange slices
\n" ); document.write( "Let $\"+b+\"$ = pounds of strawberry leaves
\n" ); document.write( "------------------------------------------
\n" ); document.write( "(1) $\"+a+%2B+b+=+13+\"$
\n" ); document.write( "(2) $\"+1.27a+%2B+1.77b+=+19.01+\"$
\n" ); document.write( "------------------------------------------
\n" ); document.write( "(2) $\"+127a+%2B+177b+=+1901+\"$
\n" ); document.write( "Multiply both sides of (1) by $\"+127+\"$
\n" ); document.write( "and subtract (1) from (2)
\n" ); document.write( "(2) $\"+127a+%2B+177b+=+1901+\"$
\n" ); document.write( "(1) $\"+-127a+-+127b+=+-1651+\"$
\n" ); document.write( "-------------------------------
\n" ); document.write( " $\"+50b+=+250+\"$
\n" ); document.write( " $\"+b+=+5+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+a+%2B+5+=+13+\"$
\n" ); document.write( "(1) $\"+a+=+8+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "8 pounds of orange slices
\n" ); document.write( "5 pounds of strawberry leaves
\n" ); document.write( "--------------------------------
