You can put this solution on YOUR website!
average of y and z= 27
\n" ); document.write( "so,
\n" ); document.write( " $\"%28y%2Bz%29%2F2+=+27\"$
\n" ); document.write( " $\"y%2Bz+=+54\"$ -----(1)
\n" ); document.write( ".
\n" ); document.write( "average of x,y and z is 32.
\n" ); document.write( "so,
\n" ); document.write( " $\"%28x%2By%2Bz%29%2F3+=+32\"$
\n" ); document.write( " $\"x%2By%2Bz+=+96\"$ -----(2)
\n" ); document.write( "from equation one we have y+z = 54.
\n" ); document.write( "so, x+ 54 = 96.
\n" ); document.write( "x= 42.
\n" ); document.write( "so, 2x= 84.
\n" ); document.write( "average of x and 2x is : $\"%2842%2B84%29%2F2+=+126%2F2+=+63+\"$
\n" ); document.write( "so, 63 is the answer of this. \n" ); document.write( "

\n" );
