gasiti numarul natural x care verifica egalitatea:
a)x+1002=2001
b)(x=13)+87=200
c)3*x+81=318
d)281 +x=2011
e)x-157=356
f)2*x+237=2013
va rog sa ma ajutati !
a) x =2001-1002=999 b)nu are cum sa fie = in paranteza c)3*x= 318-81 3*x=237 x=237:3 x=79 d)281+x=2011 x=2011-281 x=1730 e)x-157=375 x=375+157 x=532 f)2*x+237=2013 2*x=2013-237 2*x=1776 x=1776:2 x=888
