Question

calculeaza respectand ordina efectuarii operatiilor: 25×68-[2000-175:5×(84:2:7×9]:10 :::: afla valoarea lui a din egalitatile..376:8×100-[9×(139×18-10×a):3]+8905:5=3085

Answer 1

25x68-[2000-175:5x(84:2:7x9)]:10=
=1700-[2000-35x(42:7x9)]:10
=1700-[2000-35x(6x9)]:10
=1700-(2000-35x54):10
=1700-(2000-1890):10
=1700-110:10
=1700-11
=1689
:::::::::::::::::
376:8x100-[9x(139x18-10xa):3]+8905:5= 3085
47x100-[9x(2502-10a):3]+1781= 3085
470-[9x(2502-10a):3]=3085-1781
470-[9x(2502-10a):3]=1304
9x(2502-10a):3]=1304-470
9x(2502-10a):3]=834
9x(2502-10a)=834x3
9x(2502-10a)=2502
2502-10a=2502:9
2502-10a=278
10a=2502-278
10a=2224
a=2224:10
a=222,4
