Let $\"+x+\"$ = amount invested in 7% bonds
\n" ); document.write( " $\"+20000+-+x+\"$ = amount invested in 8% bonds
\n" ); document.write( "---------------------------------------
\n" ); document.write( " $\"+.07x+\"$ = profit from 7% bonds
\n" ); document.write( " $\"+.08%2A%28+20000+-+x+%29+\"$ = profit from 8% bonds
\n" ); document.write( "---------------------------------------
\n" ); document.write( "given:
\n" ); document.write( " $\"+.08%2A%28+20000+-+x+%29+=+.07x+%2B+700+\"$
\n" ); document.write( " $\"+1600+-+.08x+=+.07x+%2B+700+\"$
\n" ); document.write( " $\"+.15x+=+900+\"$
\n" ); document.write( " $\"+x+=+6000+\"$
\n" ); document.write( "She invested $6,000 in 7% bonds
