Question

calculeaza numerele x y si z stiind ca :x+y+z=759;x+y=654;y+z=328

Answer 1

x + y + z = 759

x + y = 654        } => z = 759 - 654 = 105

x + y + z = 759

y + z = 328        } => x = 759 - 328 = 431

x + y = 654

x = 431               } => y = 654 - 431 = 223

Answer 2

x+y+z=759

x+y=654 }=>z=759-654=105

x+y+z=759

y+z=328 }=>x=759-328=431

x+y=654

x=431 }=>y=654-431=223
