Let Jim's earnings= x
Let Bill's earnings= 2x-4
We are told that: Together what Jim and Bill earn is equal to what Jim earns plus what Bill earns.
That means: 95=x + (2x-4)
Solve for x.
95+4 = x + 2x
99= 3x
99/3 = x
33 = x
Therefore, Jim earns $33. Bill earns $62 because we solve: Bill's earnings= 2x -4
=2(33)-4
=66-4
=62
