You can put this solution on YOUR website!
\"four times the sum of R and S\" means that $\"4%28R%2BS%29\"$ and \"increased by twice the difference of R and S\" tells us that we add on $\"2%28R-S%29\"$ . Put this all together to get $\"4%28R%2BS%29%2B2%28R-S%29\"$ . I'll let you simplify (if you need to). \n" ); document.write( "
