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

First, let's combine like terms on both sides of the equation:

3.7 - 7.4x = 13.3 - 5.8x

Add 7.4x to both sides to get rid of the variable terms on the left side:

3.7 - 7.4x + 7.4x = 13.3 - 5.8x + 7.4x

3.7 = 13.3 + 1.6x

Subtract 13.3 from both sides:

3.7 - 13.3 = 13.3 + 1.6x - 13.3

-9.6 = 1.6x

Now, divide both sides by 1.6 to solve for x:

x = -9.6 / 1.6
x = -6

Therefore, the solution to the equation is x = -6.
