Let x = the fist number and y = the second number. \n" ); document.write( "1) y-x = 91 \"The difference of the two numbers is 91\" \n" ); document.write( "2) y = 5x-5 \"The second number is 5 less than 5 times the first\" \n" ); document.write( "Substitute the y from the second equation into the first and solve for x. \n" ); document.write( "1a) (5x-5)-x = 91 Simplify. \n" ); document.write( "5x-x-5 = 91 \n" ); document.write( "4x-5 = 91 Add 5 to both sides. \n" ); document.write( "4x = 96 Divide both sides by 4. \n" ); document.write( "x = 24 and... \n" ); document.write( "y = 5(24)-5 \n" ); document.write( "y = 120-5 \n" ); document.write( "y = 115 \n" ); document.write( "Check: \n" ); document.write( "y-x = 91 \n" ); document.write( "115-24 = 91 \n" ); document.write( "91 = 91 and... \n" ); document.write( "115 = 5(24)-5 \n" ); document.write( "115 = 120-5 \n" ); document.write( "115 = 115 \n" ); document.write( " |
