a−rl/−r=S\r
\n" ); document.write( "\n" ); document.write( "Since −r and −r are like terms, subtract r from −r to get −2r. \r
\n" ); document.write( "\n" ); document.write( "a−2r=S\r
\n" ); document.write( "\n" ); document.write( "Since −2r does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2r to both sides. \r
\n" ); document.write( "\n" ); document.write( "a=2r+S
