Greetings, 
I hope that you and your family are doing well during this pandemic. Here is how to solve the equation:
3x - 5y = -3 
What's the value for y when x = 1 
So, We need to start by replacing x with 1 
3(1) - 5y = -3
Now we solve it. 3 - 5y = -3 
-5y = -3 - 3 
-5y = -6
y = 6/5
Thus, the correct answer is 6/5
I hope this helps! Please let me know if you have additional questions. As always, it is my pleasure!
