Question

RESOLVA A EQUAÇÃO
X / 32 + Y / 7 = 6
X / 4 - Y / 14 = 14

Answer 1

 x      +   y     =  6
-----      ----- 
 32         7

7x + 32y         1344
-------------  =  --------
      224            224

7x + 32y = 1344


32,7: 2
16,7: 2
8,7: 2
4,7: 2
2,7: 2
1,7: 7
----------------
1,1  = 2.2.2.2.2.7 = 2⁵.7  =  32.7 = 224


  x     -   y       =   14
------    ------
   4        14

7x - 2y          28.14
-----------  =  ---------
     28             28

7x - 2y = 392


4,14: 2
2,7: 2
1,7: 7
--------------
1,1   = 2.2.7 = 4.7 = 28

Método da Adição:

7x + 32y = 1344
7x - 2y = 392        (-1)

7x + 32y = 1344
- 7x + 2y = - 392   (+)
-----------------------------
34y = 952
y = 952/34
y = 28

7x - 2y = 392
7x - 2.28 = 392
7x - 56 = 392
7x = 392 + 56
7x = 448
x = 448/7
x = 64

R.: y = 28 e x = 64
