Hi, so if x=0 and if y=x+5 then you would simply add 5 to x to get y, so in this case y=5. Then if x=1, then y would be 1+5, y=6. With the second part, it's the same thing. If x=1 and y=2x+3, all you have to do is multiply 1 by 2 wich = 2, then you would add 3 to that, wich is 5. And if x=2 and y=2x+3, then you would multiply 2 by 2, wich is 4, then add 3 to that wich would be 7.I hope this helps, respond to this answer if you have any comments or questions ;D
