Question

afla nr. necunoscute: a) 46513+a=100398 b) b-128314=347521. c) 800295-c=793425. d) d×7=497. e) 136:e=4.

Answer 1

a) 46513+a=100398⇔a=100398-46513⇒a=53.885
b) b-128.314=347.521⇔b=347.521+128.314⇒b=475.835
c)800.295-c=793.425⇔ -c=793.425-800.295⇒c=6.870
d) dx7=497⇔$\frac{497}{7}$⇒d=71
e)136:e=4⇔e=$\frac{136}{4}$=34
