Question

Calculați: x+y= 306 x:y= 3 restul 22 x=? ​

Answer 1

x+y= 306

y=306-x

x:y= 3 restul 22

x=3y+22

x=3(306-x)+22

x=918-3x+22 /+3x

4x=840

x=210

Answer 2

Salut!

Răspuns: 235 ✔

x + y = 306

x : y = 3 rest 22 ===> x == 3y + 22

3 y + 22 + y = 306

4 y = 306 - 22

4 y = 284

y = 284 : 4

y = 71 ✅

x = 3 x 71 + 22

x = 213 + 22

x = 235 ✅
