The difference between two numbers is 31 \n" ); document.write( "x - y = 31.......(1) \n" ); document.write( "Four times the smaller is equal to 8 more \n" ); document.write( "than the larger. \n" ); document.write( "4y = 8 + x........(20 \n" ); document.write( "Using Equation (1) \n" ); document.write( "x - y = 31 \n" ); document.write( "x = 31 + y \n" ); document.write( "Substitute x = 31 + y into equation(2) \n" ); document.write( "4y = 8 +(31 + y) \n" ); document.write( "4y = 8 + 31 + y \n" ); document.write( "Collect like terms: \n" ); document.write( "4y - y = 8 + 31 \n" ); document.write( "3y = 39 \n" ); document.write( "y = 13 \n" ); document.write( "Substitute y = 13 into Equation (1) \n" ); document.write( "x - y = 31 \n" ); document.write( "x - 13 = 31 \n" ); document.write( "x = 31 + 13 \n" ); document.write( "x = 44 \n" ); document.write( "Numbers are 44 and 13 \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
