Answer:

Rj has $138$ dollars, Shawn has $143$ dollars, and Riley has $133$ dollars.

Step-by-step explanation:

Let's make the amount of money Rj has $x$ , so Shawn would have $5+x$ dollars, and Riley would have $(5+x)-10$ dollars. Altogether they have $414$ dollars, so you can create an equation.

$x+(5+x)+((5+x)-10)=414\\3x+0=414\\3x=414\\x=138$

Now that we know that $x=138$ , we can substitute x into each equation.

Rj has $138$ dollars, Shawn has $143$ dollars, and Riley has $133$ dollars.
