You can put this solution on YOUR website!
100 - 4r = 76
\n" ); document.write( "subtract 100 from both sides
\n" ); document.write( "-4r = 76 - 100
\n" ); document.write( "-4r = -24
\n" ); document.write( "r has to be positive, multiply both sides by -1
\n" ); document.write( "4r = 24
\n" ); document.write( "divide both sides by 4
\n" ); document.write( "r = 24/4
\n" ); document.write( "r = 6
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check that in the original problem
\n" ); document.write( "100 - 4(6) = 76
\n" ); document.write( "100 - 24 = 76 \n" ); document.write( "
