Question

2 (3 - 2x) = 0,04 2 (6 - x ) = 121

Answer 1

2 * (3 - 2х) = 0,04                                     2 * (6 - х) = 121
3 - 2х = 0,04 : 2                                        6 - х = 121 : 2 
3 - 2х = 0,02                                             6 - х = 60,5
2х = 3 - 0,02                                             х = 6 - 60,5
2х = 2,98                                                  х = - 54,5   
х = 2,98 : 2                                               -----------------------------------------------
х = 1,49                                                   Проверка: 2 * (6 - (-54,5) = 121
-------------------------------                                             2 * (6 + 54,5) = 121
Проверка: 2 * (3 - 2*1,49) = 0,04                              2 * 60,5 = 121
                  2 * (3 - 2,98) = 0,04                                  121 = 121
                  2 * 0,02 = 0,04

Answer 2

To solve the equations:

1. 2(3 - 2x) = 0.04

First, distribute the 2 on the left side:

6 - 4x = 0.04

Now, isolate x by moving constants to the other side of the equation:

6 - 0.04 = 4x

5.96 = 4x

Now, divide by 4 to solve for x:

x = 5.96 / 4 x = 1.49

So, the solution to the first equation is x = 1.49.

2. 2(6 - x) = 121

First, distribute the 2 on the left side:

12 - 2x = 121

Now, isolate x by moving constants to the other side of the equation:

12 = 121 + 2x

Subtract 121 from both sides:

-109 = 2x

Now, divide by 2 to solve for x:

x = -109 / 2 x = -54.5

So, the solution to the second equation is x = -54.5.

Therefore, the solutions to the given equations are:

1. x = 1.49
2. x = -54.5
