1) To solve this equation, we first need to isolate the variable x.

7.3x - 2.4 = 107.1
7.3x = 109.5 (Adding 2.4 to both sides)
x = 109.5/7.3
x = 15

Therefore, the solution to the equation is x = 15.

2) To solve this equation, we first need to simplify the equation before isolating the variable x.

(0.24 - x) * 0.37 = 0.074
0.0888 - 0.37x = 0.074 (Expanding the left side of the equation)
-0.37x = -0.0148 (Subtracting 0.0888 from both sides)
x = -0.0148 / -0.37
x = 0.04

Therefore, the solution to the equation is x = 0.04.
