Coroana!!!Urgent!!!!!!!!!!!!!!!!!!!!

Answer 1

234 6c+2l=190, l=(190-6c)/2 inlocuim in ecuatia a doua

2c+3l=152, 2c+3(190-6c)/2=152, aducem la acelasi numitor care este2

4c+570-18c=304, 14c=570-304=266, c=266/14=19 lei

l=(190-6x19)/2=(190-114)/2=76/2=38 lei, 2x19=38,da Maria are dreptate un joc lego costa cat 2 carti

235 a=carti povesti

b= carti de poezie

c=romane

a=4b,

c=a-14

a-b=36, inlocuim pe a, 4b-b=36, 3b=36, b=36/3=12 carti de poezie

a=12x4=48 carti de povesti

c=a-14=48-12=36 romane

total carti=48+12+36=96 carti
