Let $\"+x+\"$ = the number of boys in the school
\n" ); document.write( " $\"+2%2F3+=+x%2F150+\"$
\n" ); document.write( "Multiply both sides by $\"+150+\"$
\n" ); document.write( " $\"+50%2A2+=+x+\"$
\n" ); document.write( " $\"+x+=+100+\"$
\n" ); document.write( "There are 100 boys and 150 girls, so
\n" ); document.write( " $\"+100+%2B+150+=+250+\"$
\n" ); document.write( "There are 250 students in the school
\n" ); document.write( "----------------------------------
