Question

8 – (3,54 + x) = 2,36 б) (х – 5,86) – 1,7 = 3,3

Answer 1

Пошаговое объяснение:

а) 8 - (3.54+х) = 2.36

8-х=2.36

х=2.36+8

х=10.36

3.54+х=10.36

тогда, х= 10.36 - 3.54

х= 6.82

ответ: 6,82

б) (х – 5,86) – 1,7 = 3,3

тогда, х -1.7=3.3

х=3.3 + 1.7

х=5

х - 5.86=5

найдем х,

х= 5.86 + 5

х= 10.86

ответ: 10.86

Answer 2

To solve the equations, let's simplify and isolate the variable "x" in each equation.

a) 8 - (3.54 + x) = 2.36

First, let's simplify the equation inside the parentheses:

8 - 3.54 - x = 2.36

Now, combine like terms:

4.46 - x = 2.36

Next, isolate the variable "x" by subtracting 4.46 from both sides:

-x = 2.36 - 4.46

-x = -2.1

Finally, multiply both sides by -1 to solve for "x" and change the sign:

x = 2.1

Therefore, the solution for equation (a) is x = 2.1.

b) (x - 5.86) - 1.7 = 3.3

Let's simplify the equation step by step:

x - 5.86 - 1.7 = 3.3

Combine like terms:

x - 7.56 = 3.3

Now, isolate the variable "x" by adding 7.56 to both sides:

x = 3.3 + 7.56

x = 10.86

Therefore, the solution for equation (b) is x = 10.86.
