Find two numbers who sum is 30 so that 5 times the larger number decreased by three times the smaller number is 54
\n" ); document.write( "--
\n" ); document.write( "Let S=small number
\n" ); document.write( "Let L=large number
\n" ); document.write( "--
\n" ); document.write( "given
\n" ); document.write( "S+L=30
\n" ); document.write( "5L-3S=54
\n" ); document.write( "---
\n" ); document.write( "S=30-L solve for one of the variables
\n" ); document.write( "5L-3(30-L)=54 subtitute into the other equation
\n" ); document.write( "--
\n" ); document.write( "5L-90+3L=54
\n" ); document.write( "8L-90=54
\n" ); document.write( "8L=144
\n" ); document.write( "L=144/8=18

\n" ); document.write( "\"highlight_red%28L=18%29\" and \"highlight_red%28S=30-L=12%29\"
\n" ); document.write( "==
\n" ); document.write( "validate
\n" ); document.write( "5L-3S=54
\n" ); document.write( "5(18)-3(12)=90-36=54 check
