Question

-x+3,9=2,11-x+(-5,16)=6,01

Answer 1

- х + 3,9 = 2,11

- х = 2,11 - 3,9

- х = - 1,79 / · (- 1)

х = 1,79

_____________

- 1,79 + 3,9 = 2,11

2,11 = 2,11

Ответ: х = 1,79

Второе уравнение:

- х + (-5,16) = 6,01

- х - 5,16 = 6,01

- х = 6,01 + 5,16

- х = 11,17 / · (- 1)

х = - 11,17

______________

- (- 11,17) + (- 5,16) = 6,01

11,17 - 5,16 = 6,01

6,01 = 6,01

Ответ: х = - 11,17

Удачи!!!

Answer 2

It looks like you have two equations with two variables. Let's solve them one by one.

Equation 1: -x + 3.9 = 2.11

To solve for x, we need to isolate x on one side of the equation. Let's do that:

-x + 3.9 = 2.11

Subtract 3.9 from both sides:

-x = 2.11 - 3.9

-x = -1.79

Now, to get x alone, we need to multiply both sides by -1 (since -1 * -x = x):

x = 1.79

So, the solution for the first equation is x = 1.79.

Now, let's move on to the second equation: 11 - x + (-5.16) = 6.01

To solve for x, we need to isolate x on one side of the equation. Let's do that:

11 - x - 5.16 = 6.01

Subtract 11 and -5.16 from both sides:

• x = 6.01 - 11 + 5.16

• x = -4.99

Now, to get x alone, we need to multiply both sides by -1 (since -1 * -x = x):

x = 4.99

So, the solution for the second equation is x = 4.99.

In summary, the solutions to the given equations are:

1. x = 1.79
2. x = 4.99
