Two lifeguards pull on ropes attached to a raft. If they pull in the same direction, the raft experiences a net external force of 320 N to the right. If they pull in opposite directions, the raft experiences a net external force of 109 N to the left.

(b) Find the force exerted by each lifeguard on the raft. (Disregard any other forces acting on the raft.)
N( larger force)=
N( smaller force)=

Let's call them Force A and Force B.

We know A + B = 320.

We know A = B + 109.

Substitute B + 109 + B = 320.

2B = 211

B = 105.5 N
A = 214.5 N

Simple system of equations.
