6,2 minus radical din 900 plus 4 intreg si 2 pe 5 minus X egal cu 2013

Answer 1

$6,2- \sqrt{900}+4 \frac{2}{5} -x=2013 \\ \\ 6,2-30+ \frac{22}{5}-x=2013 \\ \\ \frac{62}{10}-30+ \frac{22}{5}-x=2013 \\ \\ \frac{31}{5}-30+ \frac{22}{5}-x=2013 \\ \\ \frac{53}{5}-30-x=2013 \\ \\ x= \frac{53}{5}-30-2013 \\ \\ x= \frac{53-150-10065}{5} \\ \\ x=- \frac{10162}{5}$
