Algebra.Com's Answer #502339 by rm29924(97)![]() ![]() You can put this solution on YOUR website! let x = the first number \n" ); document.write( "let y = the second number \n" ); document.write( "the sum of the numbers is 20 \n" ); document.write( "so x+y=20 \n" ); document.write( "when the second number is subtracted by the first number the difference is 14 \n" ); document.write( "so x-y=14 \n" ); document.write( "solve for x in the second equation by adding y to both sides \n" ); document.write( "x=14+y \n" ); document.write( "now plug that value for x into the first equation \n" ); document.write( "14+y+y=20 \n" ); document.write( "14+2y=20 \n" ); document.write( "subtract 14 from both sides \n" ); document.write( "2y=6 \n" ); document.write( "divide 2 from both sides to get the variable y by itself \n" ); document.write( "y=3 \n" ); document.write( "x=14+y so x=14+3=17 \n" ); document.write( "answer: x=17 and y=3\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
