Answer 1

Maka:

Diperoleh 2 persamaan:

• 12x - 13y = 2 ... pers 1
• 10x - 10y = 8 5x - 5y = 4 .... pers 2

.

eliminasi pers 1 ke pers 2:

12x - 13y = 2 >> kalikan 5 >> 60x - 65y = 10

5x - 5y = 4 >> kalikan 12 >> 60x - 60y = 48

60x - 65y = 10

60x - 60y = 48

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

-5y = -38

y =

substitusi y ke pers 2

5x - 5y = 4

5x - 5() = 4

5x -38 = 4

5x = 4 + 38

5x = 42

x =

_________

Jadi:

x + y

=

=

= 16
