Answer 1

Я надеюсь, что всё понятно написала.

Answer 2

It looks like you have provided two equations with one variable, and it seems like you want to solve for the variable "x" in each equation. Let's solve them one by one:

1. -x + 3.9 = 2.1

Subtract 3.9 from both sides: -x = 2.1 - 3.9 -x = -1.8

Multiply both sides by -1 to solve for x: x = 1.8

So, the solution for the first equation is x = 1.8.

2. -x + (-5.16) = 6.01

Add 5.16 to both sides: -x = 6.01 + 5.16 -x = 11.17

Multiply both sides by -1 to solve for x: x = -11.17

The solution for the second equation is x = -11.17.

Please double-check the accuracy of the numbers provided in your equations to ensure the solutions are accurate.
