183 + 3 × a = 1875 , 1042-2210:b=957

Răspuns :

183 + 3 x a = 1875
3 x a = 1875 - 183
3 x a = 1692
a = 1692 : 3
a = 564

1042 - 2210 : b = 957
2210 : b = 1042 - 957
2210 : b = 85
b = 2210 : 85
b = 26
183 + 3 x a = 1875
183 + 3a = 1875
3a = 1875 - 183
3a = 1692
a = 1692 : 3 
==> a = 564
-------------------------------------------
1042 - 2210 : b = 957
2210 : b = 1042 - 957
2210 : b = 85 
b = 2210 : 85
==> b = 26

==> Succes!
