(3a+2b)/24=18 rest 16=>3a+2b=24x18+16=>3a+2b=448
(3a-2b)/(a-2b)=5=>3a-2b=5a-10b=>3a-2b-5a+10b=0=>-2a+8b=0
Cea mai simpla rezolvare este cu sistem de ecuatii, prin mtoda reducerii, ceea ce ma indoiesc ca ai invatat in clasele I-IV...
3a+2b=448=>a=(448-2b)/3
8b-2a=0=>8b=2a sau 4b=a
Egalam cele doua expresii
(448-2b)/3=4b
448-2b=12b
448=14b=>b=32=>a=128
