m+a+i=360 2x(m-50)=a+15 3x(m-50)=i+35 2x(m-50)=a+15 ⇒2m-115=a⇒2m-115 3x(m-50)=i+35⇒3m-185=i ⇒3m-185 inlocuieste a si i in prima relatie m+a+i=360⇒m+(2m-115)+(3m-185)=360 ioana are 3x60=180 deci a avut initial 3X60-35=180-35=145 andrei are 2x60=120 a avut initial 2x60-15= 120-15=105 iar mihai 60+15+35=110
