First we need to solve the first equation:

(х+3) - 5.4 = 72.85
х + 3 - 5.4 = 72.85
х - 2.4 = 72.85
х = 72.85 + 2.4
х = 75.25

Now, we can solve the second equation:

(х-23.58) + 37.6 = 150.78
х - 23.58 + 37.6 = 150.78
х + 14.02 = 150.78
х = 150.78 - 14.02
х = 136.76

Therefore, the solutions to the equations are x = 75.25 and x = 136.76.
