Question

Buna ziua va rog sa ma ajutati cu tema la matematica :
aflati termenul necunoscut din egalitatile de mai jos:
x-2002=41535-1003
a-(284-130)=110
613-(243-11-b)=549
20+h-30=150-20
853-(x+1)=249
312+11-(l+4)=323-(51+93)

Answer 1

x-2002=41535-1003
x-2002=40532
x=40532-2002
x=38530

a-(284-130)=110
a-150=110
a=110+150
a=260

613-(243-11-b)=549
613-(232-b)=549
381+b=549
b=549-381
b=168

20+h-30=150-20
h-10=130
h=130+10
h=140

853-(x+1)=249
853-x-1=249
852-x=249
-x=249-852
-x=-603 /(-1)
x=603

312+11-(l+4)=323-(51+93)
329-(l+4)=323-144
329-l-4=179
325-l=179
-l=179-325
-l=-146 /(-1)
l=146

Answer 2

1)x-2002=40532
x=40532+2002
x=42534
2)a-154=110
a=110+154
a= 256..
restu' se fac in acelas mod
b=168
h=140
x=603
l=140
