{2017-2016:[2015+2014:(2013+2012:x)]}:2016=1

Answer 1

Răspuns:

x = 2012

Explicație pas cu pas:

{2017-2016:[2015+2014:(2013+2012:x)]}:2016=1

{2017-2016:[2015+2014:(2013+2012:x)]}=1 * 2016

{2017-2016:[2015+2014:(2013+2012:x)]} = 2016

2016:[2015+2014:(2013+2012:x)]=2017-2016

2016:[2015+2014:(2013+2012:x)] = 1

2015+2014:(2013+2012:x) = 2016*1

2015+2014:(2013+2012:x) = 2016

2014:(2013+2012:x) = 2016-2015

2014:(2013+2012:x) = 1

(2013+2012:x) = 2014*1

2013+2012:x = 2014

2012:x = 2014-2013

2012:x = 1

x = 2012*1

x = 2012
