Algebra.Com's Answer #664622 by LinnW(1048)![]() ![]() You can put this solution on YOUR website! Let f = the first number \n" ); document.write( "and \n" ); document.write( "s = the second number \n" ); document.write( "s = -5 + 3f \n" ); document.write( "f+s = 23 \n" ); document.write( "solve for f by adding -s to each side \n" ); document.write( "f = 23 - s \n" ); document.write( "Substitute ( 23 - s ) for f in s = -5 + 3f \n" ); document.write( "s = -5 + 3( 23 - s ) \n" ); document.write( "s = -5 + 69 -3s \n" ); document.write( "s = 64 -3s \n" ); document.write( "add 3s to each side \n" ); document.write( "4s = 64 \n" ); document.write( "divide each side by 4 \n" ); document.write( "s = 16 \n" ); document.write( "Since s = -5 + 3f, 16 = -5 + 3f \n" ); document.write( "add 5 to each side \n" ); document.write( "21 = 3f \n" ); document.write( "divide each side by 3 \n" ); document.write( "7 = f \n" ); document.write( "The first number is 7 and the second is 16. \n" ); document.write( " \n" ); document.write( " |
