Answer 1

A). X+314=546
X=546-314
X=232

B).x-189=2357
X=2357+189
X=2546

C).2514+x=3889
X=3889-2514
X=1375

D).3456-x=1111
X=3456-1111
X=2345

E). 6400-x=1106
X=6400-1106
X=5294

F).x+501-344=5557
X=5557-501+344
X=5400

G).x+4003=5344
X=5344-4003
X=1341

H).243+x-83=856
243+x=856+83
X=939-243
X=696

I). X+3564=8743
X=8743-3564
=5179

J).983+x-51=1567
983+x=1567+51
X=1618-983
X=635

K).x+1996=4934
X=4934-1996
X=2938


L).899+x-35=1685
899+x=1685+35
X=1720-899
X=821

P.S Descazutul se afla prin adunare si scazatorul prin scadere+h,j si l fa-le tu

Explicație pas cu pas:

a)x+314=546 x=546-314=232

b)x-189=2357 x=2357+189=2546

c)2514+x=3889 x=3889-2514=1375

d)3456-x=1111 x=3456-1111=2345

e)6400-x=1106 x=6400-1106=5294

f)x+501-344=5557 x=5557+344=5901

5901-501=5400

x=5400

g)x+4003=5344 x=5344-4003= 1341

i)x+3564=8743 x=8743-3564=5169

k)x+1996=4934 x=4934-1996=2938
