Question

800 + ( 420 / X - 10 ) = 1000

Answer 1

Ответ:

х = 2

Пошаговое объяснение:

420/х - 10 = 1000 - 800

420/х - 10 = 200

420/х = 200 + 10

420/х = 210

х = 420 : 210

х = 2

Answer 2

Ответ:

x = 2

Пошаговое объяснение:

$800 + (420 / x - 10) = 1000$

$800 + 420/x - 10 = 1000$

$420/x + 790 = 1000$

$420/x=1000-790$

$420/x=210$

$420=210x$

$210x=420$

$x = 2$

Ответ: $x = 2$

Answer 3

To solve the equation for X, we need to isolate X on one side of the equation. Let's go step by step:

1. Move the constant term (800) to the other side: 800 + (420 / X - 10) - 800 = 1000 - 800

   Simplifying: 420 / X - 10 = 200

2. Add 10 to both sides to get rid of the -10 term: 420 / X = 210

3. Now, we want to isolate X, so we can get rid of the division by multiplying both sides by X: X * (420 / X) = X * 210

   The X on the left side cancels out, leaving us with: 420 = 210X

4. Finally, divide both sides by 210 to solve for X: X = 420 / 210

   Simplifying: X = 2

So, the value of X that satisfies the equation is X = 2.
