First keep in mind that the given value is negative and that it is greater than or equal to whatever 'v' is.
[tex]-8.3 \geq v - 1.9[/tex]
When solving for a variable in any equation, you do something to both sides in order to keep it equal. Here, v is being subtracted by 1.9; therefore we can add 1.9 to both sides in order to isolate the variable.
[tex]-8.3 + 1.9 \geq v - 1.9 + 1.9[/tex]
[tex]-6.4 \geq v[/tex]
Despite not needing a value for the question, it is worth noting that since this is an inequality, v can be any value from -6.4 to ∞ in order to make it true.
