Question

a÷b=6 rest 33 a-b=628 c=d×4-19 c+d=401 e=a+d

Answer 1

a:b=6 rezulta ca a=6b+33
6b+33-b=628 rezulta ca 5b=585 rezulta ca b=117
a=628+117
a=745
e=745+117
e=862
4d-19+d=401 rezulta ca 3d=420 rezulta ca d=140
c=401-140
c=261

Answer 2

a:b=6 r 33
a-b=628
c=d×4-19
c+d=401
e=a+d
-----------
a:b=6 r 33
a=6b+33
6b+33-b=628
5b=585
b=585:5
b=117
-------------
a=628+117
a=745
---------------
e=745+117
e=862
-------------
4d-19+d=401
3d=420
d=420:3
d=140
-------------
c=401-140
c=261
