Answer:
2.
Step-by-step explanation:
First keep in mind that the given value is negative and that it is
greater than or
equal to whatever '<em>v</em>' is.

When solving for a variable in any equation, you do something to both sides in order to keep it equal. Here, <em>v</em> is being subtracted by 1.9; therefore we can
add 1.9 to both sides in order to isolate <em />the variable.


Despite not needing a value for the question, it is worth noting that since this is an inequality, <em>v </em>can be any value from -6.4 to ∞ in order to make it true.
