Y=309
Y+Z=525 ​

Answer 1

Răspuns:

652

Explicație pas cu pas:

$X+Y=436\\\\Y=309\\\\ \:inlocuim\:pe\:Y\:in\:prima\:relatie\:\\\\X+309=436\\\\X = 436 - 309\\\\\boxed{X = 127}\\\\Y+Z=525\\\\309 + Z = 525\\\\Z=525-309\\\\\boxed{Z=216}\\\\\boxed{X+Y+Z=127+309+216=652}$

Answer 2

Răspuns:

Explicație pas cu pas:

x+y = 436

y = 309

x+309 = 436

x = 436-309

x = 127

y+z = 525

y = 309

309+z = 525

z = 525-309

z = 216

Suma: x+y+z = 127 + 309 + 216 = 652
