To find two consecutive integers between which the solution for the equation 3.8 = 2.1 - 0.5y lies, you can create a table and evaluate the equation for consecutive integer values of y.
Let's start with consecutive integer values for y:
| y | 2.1 - 0.5y |
|-----|-------------|
| 0 | 2.1 |
| 1 | 1.6 |
| 2 | 1.1 |
| 3 | 0.6 |
| 4 | 0.1 |
| 5 | -0.4 |
Now, we can see that the solution lies between the values of y = 4 and y = 5. So, two consecutive integers between which the solution lies are 4 and 5.
