3x - 5y = 19; x=-1,0, 1

Step-by-step explanation:

When x=-1

Substitute into the given equation

3 (-1) - 5y=19

-3-5y=19

Add 3 to both sides

-5y=22

Divide both sides by-5

y=-22/5

When x=0

3 (0) - 5y=19

0-5y=19

-5y=19

Divide both sides by-5

y=-19/5

When x=1

3 (1) - 5y=19

3-5y=19

Substrate 3 from both sides

-5y=16

Divide both sides by-5

y=-16/5

Therefore when x=-1, y=-22/5

When x=0, y=-19/5

When x=1, y=-16/5
