Question

Решите пожалуйста 1)1-(x+0,3)=0,1 2)2(x-4)=1 3)(x+1)+(x+3)=5 4)(6+2x)+x=9 5)x+1\3x=12 пожалуйста срочно!!!

Answer 1

1)1-(x+0,3)=0,1
   x + 0,3 = 1 - 0,1
   x + 0,3 = 0,9
   x = 0,9 - 0,3
   x = 0,6
______________________
1-(0,6+0,3)=0,1

Answer 2

Solution to the Equations

Let's solve the given equations step by step:

1) 1 - (x + 0.3) = 0.1

To solve this equation, we can simplify it as follows:

1 - x - 0.3 = 0.1

Now, let's isolate the variable x:

- x = 1 - 0.1 + 0.3 - x = 1.2

Therefore, the solution to the equation is x = 1.2.

2) 2(x - 4) = 1

To solve this equation, we can simplify it as follows:

2x - 8 = 1

Now, let's isolate the variable x:

- 2x = 1 + 8 - 2x = 9 - x = 9/2

Therefore, the solution to the equation is x = 4.5.

3) (x + 1) + (x + 3) = 5

To solve this equation, we can simplify it as follows:

2x + 4 = 5

Now, let's isolate the variable x:

- 2x = 5 - 4 - 2x = 1 - x = 1/2

Therefore, the solution to the equation is x = 0.5.

4) (6 + 2x) + x = 9

To solve this equation, we can simplify it as follows:

6 + 2x + x = 9

Now, let's isolate the variable x:

- 3x = 9 - 6 - 3x = 3 - x = 1

Therefore, the solution to the equation is x = 1.

5) x + (1/3)x = 12

To solve this equation, we can simplify it as follows:

(1 + 1/3)x = 12

Now, let's isolate the variable x:

- (4/3)x = 12 - x = (12 * 3)/4 - x = 36/4 - x = 9

Therefore, the solution to the equation is x = 9.

I hope this helps! Let me know if you have any further questions.
