Answer
$-1\geq v$
Work Step by Step
$4v+8\geq6v+10\longrightarrow$ subtract 4v from each side
$4v+8-4v\geq6v+10-4v\longrightarrow$ subtract
$8\geq2v+10\longrightarrow$ subtract 10 from each side
$8-10\geq2v+10-10\longrightarrow$ subtract
$-2\geq2v\longrightarrow$ divide both sides by 2
$-2\div2\geq2v\div2\longrightarrow$ divide
$-1\geq v$
