Answer 2

Ответ: x = 1

Пошаговое объяснение:

12x + 3x + 3,4 = 18,4

15x = 18,4 - 3,4

15x = 15

x = 15/15

x = 1

Answer 3

It seems like you want to solve the equation for the variable "x." Here's how you can do that:

12x + 3x + 3.4 = 18.4

Combine like terms on the left side of the equation:

(12x + 3x) + 3.4 = 18.4

15x + 3.4 = 18.4

Now, to isolate the variable x, you can subtract 3.4 from both sides of the equation:

15x = 18.4 - 3.4 15x = 15

Finally, divide both sides by 15 to solve for x:

x = 15 / 15 x = 1

So, the solution to the equation is x = 1.
