Answer 2

Ответ:

$x = \frac{3}{170}$

Пошаговое объяснение:

$(\frac{21}{34} - x) - \frac{10}{17} = \frac{1}{85}$

$-x+\frac{1}{34} = \frac{1}{85}$

$-x=-\frac{3}{170}$

$(-x)*-1=-\frac{3}{170} *-1$

$x = -\frac{3}{170} * -1$

Ответ: $x = \frac{3}{170}$

Answer 3

To solve the equation (21/34 - x) - 10/17 = 1/85, follow these steps:

Step 1: Combine like terms on the left side of the equation. Step 2: Isolate the variable x on one side of the equation. Step 3: Solve for x.

Let's go through each step:

Step 1: Combine like terms on the left side of the equation: (21/34 - x) - 10/17

To combine fractions, they need a common denominator. The common denominator for 34 and 17 is 34 * 17 = 578.

(21/34 - x) becomes (21 * 17) / 578 - x, and -10/17 becomes -10 * 34 / 578.

Now the equation becomes: (357/578 - x) - (340/578) = 1/85

Step 2: Isolate the variable x on one side of the equation:

To do this, move the constant term (340/578) to the right side of the equation by adding it to both sides:

(357/578 - x) = 1/85 + 340/578

Step 3: Solve for x:

Now, simplify the right side of the equation:

1/85 + 340/578 = (578 + 340) / (85 * 578) = 918 / 49030

The equation becomes: (357/578 - x) = 918/49030

To isolate x, subtract (357/578) from both sides:

x = 357/578 - 918/49030

Now, find a common denominator for 578 and 49030, which is 28321840.

x = (357 * 49030 - 918 * 578) / 28321840

Calculate the numerator:

x = (17522010 - 529404) / 28321840

x = 16992606 / 28321840

Now, check if the fraction can be simplified:

x = 5647535 / 9440613

So, the solution to the equation is: x = 5647535 / 9440613
