=42,4х-127,2-2х+7,2(это ответ)Надеюсь помогу

Answer 2

Let's simplify the left-hand side of the equation first:

10.6(4x-12) - 0.4(5x-18) = (104 + 0.6)(4x-12) - (0.45 + 0.4*18) = 42.4x - 127.2 - 2x + 7.2 = 40.4x - 120

Now, the equation becomes:

40.4x - 120 = 0

Adding 120 to both sides, we get:

40.4x = 120

Dividing both sides by 40.4, we get:

x = 2.970 (...rounded to three decimal places)

Therefore, the solution to the equation is x = 2.970.
