Jawaban:

(x=-2) 3x+ 2y = 12

3(-2) + 2y = 12

-6+2y=12

2y=12+6

y=18/2

y=9

(x,y) = (-2,9)

(x=-1). 3x+ 2y = 12

3(-1) + 2y = 12

-3 + 2y = 12

2y=12+3

y=15/2

(x,y) = (-1, 15/2)

(x=0) 3x+ 2y = 12

3(0) + 2y = 12

2y=12

y=12/2

y=6

(x,y) = (0,6)

(x=1) 3x+ 2y = 12

3(1) + 2y = 12

3+2y=12

2y=12-3

y=9/2

(x,y) = (1, 9/2)

(x=2) 3x+ 2y = 12

3(2) + 2y = 12

6+2y=12

2y=12-6

y=6/2

y=3

(x,y)= (2,3)

(x=3) 3x+ 2y = 12

3(3) + 2y = 12

9+2y=12

2y=12-9

y=3/2

(x,y)= (3, 3/2)

(x=4) 3x+ 2y = 12

3(4) + 2y = 12

12+2y=12

2y=12-12

y=0/2

y=0

(x,y) = (4,0)
