Question

2•x+4•x+...+4,024•x+4,020•x=2013•2014 pls

Answer 1

 2 * x + 4 * x + x + ... + • • 4,024 * x = 2 * x * (1 + 2 + 3 + .. 2012) = 2 * x * (2012 * 2013) / 2 = = x * (2012 * 2013)
1 + 2 + 3 + .... 2012 =suma gauss = (2012 * 2013) / 2
AVEM  x *  (2012 * 2013)  = 2013 * 2014 x = 2013 * 2014/2012 * 2013
x = 2014/2012
