Question

1) 23x - 13x+4,83=7,9;2) 197x –97x -1,1=8,82;​

Answer 1

1) 23х - 13х = 7,9 - 4,83

10х = 3,07

х = 0,307

2) 197х - 97х - 1,1 = 8,82

100х = 7,72

х = 0,0772

Answer 2

Ответ:

1. 0.307

2. 0.0992

Пошаговое объяснение:

Решим уравнение и вычислим неизвестно значение.

23 * x - 13 * x + 4,83 = 7,9;  

Значения с х оставляем на том же стороне, а все остальные числа перенесем на противоположную сторону.  

23 * x - 13 * x = 7.9 - 4.83;  

23 * x - 13 * x = 7 - 4 + 0.9 - 0.83;  

23 * x - 13 * x = 3 + 0.07;  

23 * x - 13 * x = 3.07;  

x  * (23 - 13) = 3.07;  

x * 10 = 3.07;  

x = 3.07/10;  

x = 0.307;  

Ответ: х = 0,307.  

2) 197 * x - 97 * x - 1,1 = 8,82;  

197 * x - 97 * x = 8.82 + 1.1;  

197 * x - 97 * x = 9.92;  

x * (197 - 97) = 9.92;  

x * 100 = 9.92;  

x = 9.92/100;  

x = 0.0992;  

Ответ: х = 0,0992.

Answer 3

To solve these equations, you can follow these steps:

Equation 1: 23x - 13x + 4.83 = 7.9

Step 1: Combine like terms on the left side of the equation:

(23x - 13x) + 4.83 = 7.9 10x + 4.83 = 7.9

Step 2: Isolate the variable term (10x) by subtracting 4.83 from both sides:

10x = 7.9 - 4.83 10x = 3.07

Step 3: Solve for x by dividing both sides by 10:

x = 3.07 / 10 x = 0.307

Equation 2: 197x - 97x - 1.1 = 8.82

Step 1: Combine like terms on the left side of the equation:

(197x - 97x) - 1.1 = 8.82 100x - 1.1 = 8.82

Step 2: Isolate the variable term (100x) by adding 1.1 to both sides:

100x = 8.82 + 1.1 100x = 9.92

Step 3: Solve for x by dividing both sides by 100:

x = 9.92 / 100 x = 0.0992

So, the solutions to the equations are:

1. x = 0.307
2. x = 0.0992
