( liters of blue paint ) / ( liters of yellow paint ) = 2/3
\n" ); document.write( "Let $\"+x+\"$ = liters of yellow paint needed
\n" ); document.write( "given:
\n" ); document.write( "He has $\"+15+\"$ liters of blue paint
\n" ); document.write( "------------
\n" ); document.write( " $\"+15%2Fx+=+2%2F3+\"$
\n" ); document.write( "Multiply both sides by $\"+3x+\"$
\n" ); document.write( " $\"+45+=+2x+\"$
\n" ); document.write( " $\"+x+=+22.5+\"$
\n" ); document.write( "He should buy 22.5 liters of yellow paint
\n" ); document.write( "He can make $\"+15+%2B+22.5+=+37.5+\"$ liters of green paint \n" ); document.write( "
