dau coroana cine ma ajuta

Answer 1

a)x=2814-1473=1341
b)73+x=123+41
   x=91
c)436+x=2045
   x=2045-436=1609
d)77+x+124=392+17
  201+x=409
  x=409-201=207
e)65+x+173=2*(159+252)=822
   x=822-65-173=584
f)98+2x+122=4*180=720
2x=720-122-98=500  x=500:2=250
g)15+143+2x+6=2*100+288=488
2x=488-15-6-143=324
x=324:2=162
h)28+230+2x+10=3*(81-35)*101
268+2x=13938
2x=13938-268=13670
x=13670:2
x=6835
