Question

X+y+z=759
X+y=654
Y+z=328
X=?
Y=?
Z=?

Answer 1

x+ y+ z = 759

x+ y=654

y+z=328

654+ z = 759

z=759-654

z=105

328+y=759

y=759-328

y=431

x+431+105=759

x+536=759

x=223

VERIFICARE 223+431+105 = 759

Answer 2

X+y+z=759
654+z=759
Z=105
Y+z =328
Y=328-105
Y=223
X+y =654
X=654-223
X=431
