Trebuie sa rezolv dupa modelul acesta:
(exemplu)
1592-y+64=377
1592-y=377-64
1592-y=31
y=1592-313
y=1279
1592-1279=313
Va rog,ajutati-ma!!!!!

Answer 1

a) 8100-y-1540=2066
8100-y=2066+1540
8100-y=3606
y=8100-3606
y=4494
b) 2702-y+339=1001
2702-y=1001-339
2702-y=662
y=2702-662
y=2040
c) )4311+y-8=9137
4311+y=9137+8
4311+y=9145
y=9145-4311
y=4834
d) y-26-3400=196
y-26=196+3400
y-26=3596
y=3596+26
y=3622
