Calculati nr. Natural x pentru care:
a) 8-(18-6):6=[8-3*(9-7)]* x
b) [(124 +150 -x):31-2=0
c)128-[48+6*7-(x:3+15)]:3=104
Merci!! :*

Răspuns :

a)8-2=(8-6)x
6=2x =>x=3

b)(274-x):31=2
274-x=62
x=274-62 =>x=212

c)128-[48+42-(x:3+15)]:3=104
128-(90-x/3-15):3=104
90-x/3-15=(128-104)·3
75-x/3=72
x/3=3 =>x=9
