Work Step by Step

$3(2+t)\geq15-2t\longrightarrow$ multiply using the distributive property $6+3t\geq15-2t\longrightarrow$ add 2t to each side $6+3t+2t\geq15-2t+2t\longrightarrow$ add $6+5t\geq15\longrightarrow$ subtract 6 from each side $6+5t-6\geq15-6\longrightarrow$ subtract $5t\geq9\longrightarrow$ divide both sides by 5 $5t\div5\geq9\div5\longrightarrow$ divide $t\geq1\frac{4}{5}$
