1. Two numebers have a sum of 26. Three times the first less twice the second is 3. Find the numbers.\r
\n" ); document.write( "\n" ); document.write( "1.x+y=26
\n" ); document.write( "2.3x-2y=3
\n" ); document.write( "multiply eq1 by 2 and add the equationa
\n" ); document.write( "2x+2y+3x-2y=52+3
\n" ); document.write( "5x=55
\n" ); document.write( "x=11
\n" ); document.write( "y=26-11=15
\n" ); document.write( "..\r
\n" ); document.write( "\n" ); document.write( "2. Two numbers differ by 7. Three times the larger is five times the smaller olus 3. Find the length.\r
\n" ); document.write( "\n" ); document.write( "1.x-y=7
\n" ); document.write( "3x=5y+3
\n" ); document.write( "2.3x-5y=3\r
\n" ); document.write( "\n" ); document.write( "multiply eq1 by 5 and add the equations
