Answer:

see below

Explanation:

I find it convenient to factor 5 from the equation and re-order the left side:

y -2x = 3

This makes it relatively easy to see that the values in the left-most table will satisfy this equation.

__

If we look at the table values for x=2, where all the tables differ, we can easily find the one that works:

1. 7 -2(2) = 3 . . . . this value works in the equation

2. 0.5 -2(2) = -3.5 . . . . no

3. -1 -2(2) = -5 . . . . no

4. 2.5 -2(2) = -1.5 . . . . no
