write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"A pet store has a total of 35 dogs,cats,and rabbits.\"
\n" ); document.write( "d + c + r = 35
\n" ); document.write( ":
\n" ); document.write( "\"the number of rabbits is 1 more than dogs,\"
\n" ); document.write( "r = d + 1
\n" ); document.write( "d = r - 1
\n" ); document.write( ":
\n" ); document.write( "\" and there are 3 fewer rabbits than cats.\"
\n" ); document.write( "r = c - 3
\n" ); document.write( "c = r + 3
\n" ); document.write( ":
\n" ); document.write( "Find the number of rabbits using the 1st equation:
\n" ); document.write( "d + c + r = 35
\n" ); document.write( "Substitute for d and c
\n" ); document.write( "(r-1) + (r+3) + r = 35
\n" ); document.write( "3r + 2 = 35
\n" ); document.write( "3r = 35 - 2
\n" ); document.write( "3r = 33
\n" ); document.write( "r = 33/3
\n" ); document.write( "r = 11 rabbits
\n" ); document.write( ":
\n" ); document.write( " how many cats are in the pet store
\n" ); document.write( "c = r + 3
\n" ); document.write( "c = 11 + 3
\n" ); document.write( " c = 14 cats \n" ); document.write( "
\n" );
