Question

- (6,2-x) +7,2=2,2решите уровнение ​

Answer 1

-(6,2-х)+7,2=2,2
-6,2+х+7,2=2,2
1+x=2,2
x=2,2-1
x=1,2

Answer 2

To solve the equation, let's simplify and isolate the variable.

Starting with the equation:

-(6, 2 - x) + 7, 2 = 2, 2

First, distribute the negative sign to the terms inside the parentheses:

-6 - (2 - x) + 7, 2 = 2, 2

Next, simplify the expression within the parentheses:

-6 - 2 + x + 7, 2 = 2, 2

Combine like terms:

-8 + x + 7, 2 = 2, 2

Now, subtract 7.2 from both sides to isolate the variable:

-8 + x = 2, 2 - 7, 2

Simplifying further:

-8 + x = -5

Finally, to solve for x, add 8 to both sides:

x = -5 + 8

x = 3

Therefore, the solution to the equation -(6, 2 - x) + 7, 2 = 2, 2 is x = 3.
