3a+2b=48
\n" ); document.write( "(a+b)/2=7
\n" ); document.write( "a+b=14
\n" ); document.write( "a=14-b
\n" ); document.write( "3(14-b)+2b=48
\n" ); document.write( "42-3b+2b=48
\n" ); document.write( "-b=48-42
\n" ); document.write( "-b=6
\n" ); document.write( "b=-6 answer.
\n" ); document.write( "3a+2*-6=48
\n" ); document.write( "3a-12=48
\n" ); document.write( "3a=48+12
\n" ); document.write( "3a=60
\n" ); document.write( "a=60/3
\n" ); document.write( "a=20 answer.
\n" ); document.write( "(20-6)/2=7
\n" ); document.write( "14/2=7
\n" ); document.write( "7=7
\n" ); document.write( " \n" ); document.write( "
