3x-5y=19; x= -1,0,1
Answer:
When X = -1, y = -2.4
When X = 0, y = -1.8
When X = 1, y = -1.2
Step-by-step explanation:
When X = -1
3x - 5y = 9
3(-1) - 5y = 9
-3 - 5y = 9
-5y = 9 + 3
-5y = 12
y = 12/-5
y = -2.4
When X = 0
3x - 5y = 9
3(0) - 5y = 9
0 - 5y = 9
-5y = 9
y = 9/-5
y = -1.8
When x = 1
3x - 5y = 9
3(1) - 5y = 9
3 - 5y = 9
-5y = 9 - 3
-5y = 6
y = 6/-5
y = - 1.2
