Va rogg, ajutati-ma

Answer 1

1)
a) x+536=803
x=803-536
x=267
b) x-1107=325
x=325+1107
x=1432
c) 1000-x=196
1000-196=x
x=804

2)
a) (374+926)-x=518
1300-x=518
1300-518=x
x=782

b) x+(2015-964)=1247
x+1051=1247
x=1247-1051
x=196

Answer 2

a+536=803   b-1107=325  1000-c=196 (374+926)-a=518   (2015-964)+b=1247
