Let's first distribute the terms inside the parentheses:

3 4 2 + 3 4 5x + 4 2 - 4 2.7x = 1.4 - 1.5x

Now we simplify each term:

12 + 12x + 8 - 10.8x = 1.4 - 1.5x

Combine like terms:

20 + 1.2x = 1.4 - 1.5x

Now, let's isolate the variables:

1.2x + 1.5x = 1.4 - 20

2.7x = -18.6

x = -18.6 / 2.7

x ≈ -6.88

Therefore, the solution to the equation is x ≈ -6.88.
