Question

Exercitiuuu 15 punctele b) şi c) va roggg

Answer 1

b) x=|-46|-(-91)-200

x=46+91-200

x=137-200

x= -63

y=108-|415|-(-25)

y=108-415+25

y= -307+25

y= -282

x-y=

= -63-(-282)=

= -63+282= -219

y-(-x)=

=y+x=

= -282+(-63)=

= -282-63= -345

c) x=127-355-(-41)

x= -288+41

x= -247

y=(-69)-|-54|-|283|

y= -69-54-283

y= -123-283

y= -406

x-y=

= -247-(-406)=

= -247+406=159

y-(-x)=

=y+x=

= -406+(-247)=

= -406-247= -653

Answer 2

$\it b)\ x=|46|-(-91)-200=46+91-200=137-200=-63\\ \\ y=108-|415|-(-25)=108-415+25=133-415=-282\\ \\ x-y=-65-(-282)=-63+282=219\\ \\ y-(-x)=y+x=-282+(-63)=-282-63=-345$
