Question

1/2х + 1/4х + 1/7х = х

Answer 1

Ответ:

x = 0

Пошаговое объяснение:

$\frac{1}{2} x + \frac{1}{4} x + \frac{1}{7} x = x\\\\14x + 7x + 4x = 28x\\\\25x = 28x\\\\25x - 28x = 0\\\\-3x = 0\\\\x =0$

Answer 2

Ответ: 0
1/2x + 1/4x + 1/7x = x / *28
14x + 7x + 4x = 28x
25x = 28x
25x - 28x = 0
-3x = 0
x = 0/-3
x = - 0/3
x = 0

Answer 3

To solve the equation:

1/2x + 1/4x + 1/7x = x

We need to find the value of x that satisfies the equation.

First, let's find a common denominator for the fractions on the left side of the equation. The least common multiple of 2, 4, and 7 is 28. So, we can rewrite the equation as:

(14/28)x + (7/28)x + (4/28)x = x

Now, let's combine the fractions:

(14/28 + 7/28 + 4/28)x = x

(25/28)x = x

To eliminate the fraction, we can multiply both sides of the equation by the reciprocal of (25/28), which is (28/25):

(28/25)(25/28)x = (28/25)x

x cancels out on the left side, and we're left with:

28/25 = x

Therefore, the solution to the equation is:

x = 28/25
