Question

intr-0 padure sunt 961de fagi,stejari si brazi. fagii si stejarii la un loc sunt855 ,iar stejari si brazi impreuna sunt 282 .cati f,s,b sunt?

Answer 1

f + s + b = 961 f + s = 855 s + b = 282 => b = 961 - 855 = 106 f = 961 - 282 = 679 s = 961 - ( 106 + 679 ) = 176

Answer 2

f+s+b=961
f+s=855
s+b=282

855+b=961
b=961-855
b=106

s+106=282
s=282-106
s=176

f+176=855
f=855-176
f=679
R:f=679;s=176;b=106.
