Question

determina-l pe x : 10 - (1+5 : x) x 4 = 2
15 + 5 x {5 + 5 : [45 : 5- (36 : x + 4)] + 6 x 0} = 65 ...... REPEDE !!!! 20 puncte + coroana ..... (vreau rezolvare , nu direct raspunsul ..... cine da doar raspunsul primeste report )

Answer 1

1))
(1+5:x)x4 = 10-2
=1+5:x= 8:4
= 5:x= 2-1
X= 5x1
X= 5
-------
2)))
15+5 x{5+5:[9-(36:X-4)]+0}= 65
=5 x{5+5:[9-(36:X-4)]=65-15
= 5+5:[9-(36:X-4)]= 50:5
= 5+5:[9-(36:X-4)]= 10
= 5:[9-(36:X-4)]=10-5
= 5:[9-(36:X-4)]=5
= 9-(36:X-4)= 5:5
=9-(36:X-4)=1
= 36:X-4= 9-1
= 36:X-4= 8
= 36:X= 8+4
= 36:X= 12
X= 36:12
X= 3
Sper ca te-am ajutat !!
