4x+2y=112
x+y=44
x=?
y=?


Sagot :

Cevap:

x = 12

y = 32

Adım adım açıklama:

4x + 2y = 112   ise  eşitliğin her iki tarafını da 2'ye bölersek denklemimiz

2x + y = 56 olur.

2x + y = 56

 x + y = 44               taraf tarafa çıkarırsak

-----------------

2x + y - x - y = 56 - 44

x = 12

x + y = 44

12 + y = 44

y = 44 - 12 = 32
