Algebra.Com's Answer #493318 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! Let x - one number and y = the other. Then: \n" ); document.write( "x + y = 94 \n" ); document.write( "x*y = 360 \n" ); document.write( "We will use the Substitution Method to solve. Solving the first equation for y we get: \n" ); document.write( "y = -x + 94 \n" ); document.write( "Substituting for y in the other equation: \n" ); document.write( "x*(-x+94) = 360 \n" ); document.write( "Now we solve this. First we simplify: \n" ); document.write( " \n" ); document.write( "Since this is a quadratic equation we want one side to be zero. Since I also like a positive coefficient in fromt of \n" ); document.write( " \n" ); document.write( "Next we factor: \n" ); document.write( "0 = (x-90)(x-4) \n" ); document.write( "Zero Product Property: \n" ); document.write( "x-90 = 0 or x-4 = 0 \n" ); document.write( "Solving these: \n" ); document.write( "x = 90 or x = 4 \n" ); document.write( "Finding y (using y = -x + 94): \n" ); document.write( "For x = 90: y = -(90) + 94 = 4 \n" ); document.write( "For x = 4: y = -(4) + 94 = 90 \n" ); document.write( "So the two numbers are 4 and 90. \n" ); document.write( " |
