Algebra.Com's Answer #165859 by scott8148(6628) You can put this solution on YOUR website! multiplying 1st eqn by 5 ___ 25r - 10s = 40\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "multiplying 2nd eqn by 2 ___ 4r + 10s = 76\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "adding new eqns (this eliminates the s terms) ___ 29r = 116 ___ r = 4\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "substituting ___ 2(4) + 5s = 38 ___ 5s = 30 ___ s = 6 \n" ); document.write( " |
