Question

exercitiul 4 si 3
la 3 doar punctul b si c
va rogggg

Answer 1

b) 9538+n-1279=908708
n=908707-9538+1279
n=908708-8262
n=900446

c)n-15699+3245=809586
n-12454=809586
n=809586+12454
n=822040

4/ 1) x+y=200000+12345=212345
(x+y)-z=212345-99999=112346
2)x=?
y=300000
z=?
x+y=901000
(x+y)-z=799895

x+300000=901000
x=901000-300000
x=601000

901000-z=799895
-z=799895-901000
-z=-101105
z=101105

3) x=3040
y=?
z=88
x+y=90100
(x+y)-z=?

3040+y=90100
y=90100-3040
y=87060

90100-88=90012
