Question

Х+356=2400÷6с*(107-890)=414D÷15+706=1002

Answer 1

Первое:
X+356=2400:6
x+356=400
x=400-356
x=44

Answer 2

It appears you've written a mathematical expression with some variables and operations. Let's break it down step by step:

1. Х + 356 = 2400 ÷ 6с * (107 - 890) = 414D ÷ 15 + 706 = 1002

We have several variables here: Х, с, and D. We also have some operations like addition (+), subtraction (-), multiplication (*), and division (/).

However, there seems to be some confusion in the expression as written. The symbols с and D are typically not used as variables in mathematics, and it's unclear how they should be interpreted. Additionally, the expression within the parentheses seems to have a mathematical error because the result of (107 - 890) is negative, and it's not clear how you intend to handle it.

If you could clarify the meanings of с and D and provide a more specific question or equation, I would be happy to help you with your math problem.
