Question

21 va rog am nevoie Urgent

Answer 1

a) x=1453-783=670
b) x=2941+633=3573
c) x-159=267
x=267+159=426
d) 425+x=638
x=638-425=213
e) (43+x)+323=975
43+x=975-323
43+x=652
x=652-43=609

Answer 2

1453 - x = 783
1453 - 783 = x
670 = x

x - 633 = 2941
x = 2941 + 633
x = 3574

x - 67 - 92 = 267
x = 267 + 67 + 92
x= 426

542 + x - 117 = 638
x = 638 - 542 + 117
x = 213

(43 + x ) + ( 537 - 214 ) = 975
43 + x + 323 = 975
x = 975 - 323 - 43
x = 609
