Question

Determină valoarea lui a din fiecare egalitate:
f(114-63:9)+a-(1011-164×4)=66
i[(2960:a-11):7+990]:999=3
l[(a-8000):50+900]:4=250
y[(163×4+a):100+182]:2+20×5=196
va rog frumos am nevoie urgent
vă rog verificare aici
dau coroană ​

Answer 1

Răspuns:

f(114-63:9)+a-(1011-164×4)=66

114-7+a-(1011-41)=66

107+a-970=66

a=929

i[(2960:a-11):7+990]:999=3

[(2960:a-11):7+990]:999=3

(2960:a-11):7=2997-990=2007

2960:a-11=2007×7=14049

2960:a=14060

a=0,2105

l[(a-8000):50+900]:4=250

(a-8000):50=250×4-900

a-8000=(1000-900)×50=5000

a=13000

y[(163×4+a):100+182]:2+20×5=196

(163×4+a):100+182=(196-100)×2

(652+a):100=192-182=10

652+a=10×100=1000

a=1000-652

a=342
