Question

rezolvati in multimea numerelor naturale ecuatia [(x-8):100+30]:10-70=0

Answer 1

Răspuns

↓

[ ( x - 8 ) : 100 + 30 ] : 10 - 70 = 0

[ ( x - 8 ) : 100 + 30 ] : 10 = 0 + 70 = 70

( x - 8 ) : 100 + 30 = 70 × 10 = 700

( x - 8 ) : 100 = 700 × 100 = 70000

x - 8 = 70000 + 8 = 70008

$x \: - 8 = 70008$
$x = 70008 - 8$
$x = 70000$

Answer 2

[(x-8):100+30]:10-70=0

0+70=70

[(x-8):100+30]:10=70

70×10=700

(x-8):100+30=700

700-30=670

(x-8):100=630

630×100=63000

x-8=63000

x=63000-8

x=62992
