How Do You Solve For Y=5x, Can You Let X=-3,0,2?

It can be solved in a number of ways.
1) if you consider x= -3, then the Y= 5(-3)=> -15.
2) if you consider x=0, then Y=5(0)=> 0.
3) if you consider x=2, then Y=5(2)=> 10.

1.it can't be solved
2. If you are asking to solve by assuming x=-3,0,2 then it can be.
