Work Step by Step

$4(3n-1)\geq2(n+3)\longrightarrow$ multiply using the distributive property $12n-4\geq2n+6\longrightarrow$ subtract 2n from each side $12n-4-2n\geq2n+6-2n\longrightarrow$ subtract $10n-4\geq6\longrightarrow$ add 4 to each side $10n-4+4\geq6+4\longrightarrow$ add $10n\geq10\longrightarrow$ divide each side by 10 $10n\div10\geq10\div10\longrightarrow$ divide $n\geq1$
