say a+b= 15
\n" ); document.write( "Then the sum of twice the first and thrice the second is 35
\n" ); document.write( "So, 2a+3b= 35\r
\n" ); document.write( "\n" ); document.write( "We have;
\n" ); document.write( "a+b=15 ---i
\n" ); document.write( "2a+3b=35 ---ii\r
\n" ); document.write( "\n" ); document.write( "Then a=15-b ---iii\r
\n" ); document.write( "\n" ); document.write( "Input a into eqn ii
\n" ); document.write( "2(15-b)+3b= 35
\n" ); document.write( "30-2b+3b= 35
\n" ); document.write( "Collect like terms
\n" ); document.write( "-2b+3b=35-30
\n" ); document.write( "b=5.\r
\n" ); document.write( "\n" ); document.write( "Input b into eqn i
\n" ); document.write( "a+5=15
\n" ); document.write( "a=15-5
\n" ); document.write( "a=10. a=10, b=5.
\n" ); document.write( "
\n" );
