Answer
$n=4$
Work Step by Step
$6+2(3n-1)=28$ $\longrightarrow$distributive property
$6+6n-2=28$ $\longrightarrow$combine like terms
$4+6n=28$ $\longrightarrow$addition property
$4+6n-4=28-4$ $\longrightarrow$combine like terms
$6n=24$ $\longrightarrow$multiplication property
$6n\div6=24\div6$ $\longrightarrow$divide
$n=4$
