Let t=income from teaching, p=income from painting, b=income from book sales.
\n" ); document.write( "t=p+6000
\n" ); document.write( "b=(t+p)/7
\n" ); document.write( "b+t+p=48000
\n" ); document.write( "(t+p)/7 +p+6000+p=48000 substitute
\n" ); document.write( "(p+6000+p)/7 + p+6000 + p = 48000 more substitution
\n" ); document.write( "(2p+6000)/7 + p+6000 + p = 48000
\n" ); document.write( "(2p+6000) + 7(p+6000) + 7p = 7*48000 multiply each side by 7 to eliminate the fraction.
\n" ); document.write( "2p+6000+7p+42000+7p=336000
\n" ); document.write( "16p+48000=336000
\n" ); document.write( "16p=336000-48000
\n" ); document.write( "16p=288000
\n" ); document.write( "16p/16=288000/16
\n" ); document.write( "p=$18,000.
\n" ); document.write( ".
\n" ); document.write( "t=18000+6000
\n" ); document.write( "t=$24,000.
\n" ); document.write( ".
\n" ); document.write( "b=(24000+18000)/7
\n" ); document.write( "=42000/7
