Question

17,9+(4-x)=10,9 Правильный ответ

Answer 1

Ответ:

х≈3,4

Пошаговое объяснение:

17,9+(4-x)=10,9

71,6-17,9х=10,9

-17,9х=10,9-71,6

-17,9х= -60,7

х≈3,4

Answer 2

To find the value of x, we need to isolate it on one side of the equation. Let's solve the equation step-by-step:

1. Start by subtracting 9 from both sides to get rid of the constant on the left side of the equation: 17.9 + (4 - x) - 9 = 10.9 - 9

Simplifying the left side: 17.9 + (4 - x) - 9 = 12.9 - x

2. Now, let's simplify the left side by combining like terms: (4 - x) - 9 = 12.9 - x

Simplify further:

• x - 5 = 12.9 - x

3. Next, we want to isolate x on one side. To do this, let's add x to both sides of the equation:

• x - x - 5 = 12.9 - x + x

Simplifying:

• 2x - 5 = 12.9

4. Now, add 5 to both sides to eliminate the constant term on the left side:

• 2x - 5 + 5 = 12.9 + 5

Simplifying:

• 2x = 17.9

5. Finally, to solve for x, divide both sides by -2: x = 17.9 / -2 x = -8.95

So, the correct value of x is -8.95.
