\"Four times a number added to another number is 36. Three times the first number minus the other number is 20. Can you please tell me the numbers.\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = the number
\n" ); document.write( "y = other number\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x + y = 36 {four times a number added to another number is 36}
\n" ); document.write( "3x - y = 20 {three times the 1st minus other is 20}
\n" ); document.write( "-----------
\n" ); document.write( "7x = 56 {added the two equations together and eliminated the y}
\n" ); document.write( "x = 8 {divided both sides by 7}
\n" ); document.write( "The first number is 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x + y = 36 {top equation}
\n" ); document.write( "4(8) + y = 36 {substituted 8 in for x}
\n" ); document.write( "32 + y = 36 {multiplied 4 by 8}
\n" ); document.write( "y = 4 {subtracted 32 from both sides}
\n" ); document.write( "The other number is 4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "8 and 4 are the two numbers.\r
