Algebra.Com's Answer #26416 by psbhowmick(878) You can put this solution on YOUR website! Let first number = x and second number = y. \n" ); document.write( "Their sum: x + y = 34 _________(1) \n" ); document.write( "3 times first number: 3x \n" ); document.write( "So the equation becomes y = 3x - 4 _________(2) \n" ); document.write( "Put the value of y from (2) in (1); then you find \n" ); document.write( "x + (3x - 4) = 34 \n" ); document.write( "or 4x = 34 + 4 = 38 \n" ); document.write( "or x = 38/4 = 19/2 \n" ); document.write( "So from (2), y = 49/2 \n" ); document.write( "Thus the numbers are 19/2 & 49/2 respectively.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Try the next one yourself exactly as the above solution. \n" ); document.write( "The equations are: x + y = 92 & y = 3x + 4. \n" ); document.write( "Answer: The numbers is 22 & 70. \n" ); document.write( " |
