( olive oil ) / ( vinegar ) = 2/1
\n" ); document.write( "Let $\"+x+\"$ = ounces of vinegar needed
\n" ); document.write( " $\"+42+-+x+\"$ = ounces of olive oil needed
\n" ); document.write( " $\"+2%2F1+=+%28+42-x+%29+%2F+x+\"$
\n" ); document.write( "Multiply both sides by $\"+x+\"$
\n" ); document.write( " $\"+2x+=+42+-+x+\"$
\n" ); document.write( " $\"+3x+=+42+\"$
\n" ); document.write( " $\"+x+=+14+\"$
\n" ); document.write( " $\"+42+-+x+=+28+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "28 ounces of olive oil are needed
