To solve the equation, we can start by simplifying both sides:

2.3x - 405 = 3x - 1

First, let's get rid of the decimal by multiplying every term by 10:

23x - 4050 = 30x - 10

Next, let's isolate the x terms by subtracting 23x from both sides:

-4050 = 7x - 10

Now, let's isolate the constant term by adding 10 to both sides:

-4040 = 7x

Finally, we can solve for x by dividing both sides by 7:

x = -4040/7

Therefore, the solution to the equation is x = -4040/7.
