Dominick weighs 30 pounds more than his sister. Together they weigh 330 pounds. How much does Dominick weigh?

Domik weights 30 pounds more than his sister

Together they weigh 330 pounds

Let "x" represent the weight of Dominik's sister, then his weight can be expressed as "x+30"

And their total weight can be calculated as:

$x+(x+30)=330$

From this expression you can calculate the value of x:

$\begin{gathered} 2x+30=330 \\ 2x+30-30=330-30 \\ 2x=300 \\ \frac{2x}{2}=\frac{300}{2} \\ x=150 \end{gathered}$

x=150 pounds

x+30=150+30=180 pounds

Dominik weights 180pounds and his sister 150 pounds
