b+3070-1,814=2500

b+3070=2500+1814

b=4,314-3070

b=1,244

c)

c-998-(7014-5843)=5843-3485

c-998-(7014-5843)=2,358

c-998-1,171=2,358

c-998=2,358+1,171

c-998=3,529

Answer 2

Răspuns:

a) 3737 b) 1244 c)4527

Explicație pas cu pas:

a) a+719 = 1913+2543

a+719 = 4456

a = 4456-719

a = 3737

b) a+3070 -(917+897) = 2500

a+3070 = 2500+1814

a+3070 = 4314

a = 4314-3070

a = 1244

c) a-998-(7014-5843) = 5843-3485

a-998-1171 = 2358

a = 2358+1171+998

a = 4527
