Let the bigger number be x and the smaller number be y. \n" ); document.write( "x + y = 29 \n" ); document.write( "and \n" ); document.write( "x - 4y = 4 \n" ); document.write( "Rewrite the first equation as x = 29 - y \n" ); document.write( "Substitute this equation into the second one to get \n" ); document.write( "29 - y - 4y = 4 \n" ); document.write( "i.e. 29 - 5y =4 \n" ); document.write( "Add 5y to each side of the equation \n" ); document.write( "29 - 5y + 5y = 4 + 5y \n" ); document.write( "i.e. 29 = 4 + 5y \n" ); document.write( "Subtract 4 from each side of the equation \n" ); document.write( "29 - 4 = 4 + 5y - 4 \n" ); document.write( "i.e. 25 = 5y \n" ); document.write( "i.e. y = 5 \n" ); document.write( "If the two numbers add to make 29 then the second number(x) must be 24. \n" ); document.write( " \n" ); document.write( " |
