You can put this solution on YOUR website!
0.4r - 1.2 = 0.3r + 0.6
\n" ); document.write( ":
\n" ); document.write( "Get rid of the decimals, multiply equation by 10
\n" ); document.write( "4r - 12 = 3r + 6
\n" ); document.write( ":
\n" ); document.write( "Subtract 3r from both sides:
\n" ); document.write( "4r - 3r - 12 = 6
\n" ); document.write( ":
\n" ); document.write( "Add 12 to both sides
\n" ); document.write( "r = 6 + 12
\n" ); document.write( ":
\n" ); document.write( "r = 18
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in original equation, replace r with 18:
\n" ); document.write( "0.4(18) - 1.2 = 0.3(18) + 0.6
\n" ); document.write( "7.2 - 1.2 = 5.4 + .6
\n" ); document.write( "6 = 6; confirms our solution of r=18 \n" ); document.write( "

\n" );
