3,5 x + 4.18 =81 Розписати ​

Answer 1

Пошаговое объяснение:

3,5х + 4,18 = 81

3,5х = 81 - 4,18

3,5х = 76,82

х = 76,82 : 3,5

х = 7682/100 : 35/10

х = 7682/100 * 10/35

х = 7682/10 * 1/35

х = 7682/350

х = 21 332/350

х = 21 166/175

Answer 2

To solve the equation 3.5x + 4.18 = 81, we'll isolate the variable x. Here are the steps:

1. Subtract 4.18 from both sides of the equation: 3.5x + 4.18 - 4.18 = 81 - 4.18 3.5x = 76.82

2. Divide both sides of the equation by 3.5 to solve for x: (3.5x)/3.5 = 76.82/3.5 x = 22

Therefore, the solution to the equation 3.5x + 4.18 = 81 is x = 22.

Answer 3

To solve the equation 3.5x + 4.18 = 81, we'll isolate the variable x. Here are the steps:

1. Subtract 4.18 from both sides of the equation: 3.5x + 4.18 - 4.18 = 81 - 4.18 3.5x = 76.82

2. Divide both sides of the equation by 3.5 to solve for x: (3.5x)/3.5 = 76.82/3.5 x = 22

Therefore, the solution to the equation 3.5x + 4.18 = 81 is x = 22.
