Answer 2

640/700-(х+260/700)=50/700​

640/700-x-260/700=50/700

19/35-x=50/700

-x=-33/70

x=33/70

Answer 3

To solve the equation $\frac{640}{700} - \left(\frac{x}{700} + \frac{260}{700}\right) = \frac{50}{700}$, you can follow these steps:

Step 1: Simplify the equation by finding a common denominator for all fractions, which is 700 in this case:

$\frac{640}{700} - \left(\frac{x}{700} + \frac{260}{700}\right) = \frac{50}{700}$

Step 2: Subtract the fractions within the parentheses:

$\frac{640}{700} - \frac{x}{700} - \frac{260}{700} = \frac{50}{700}$

Step 3: Combine the fractions on the left side:

$\frac{640 - x - 260}{700} = \frac{50}{700}$

Step 4: Continue to simplify:

$\frac{380 - x}{700} = \frac{50}{700}$

Step 5: Now, set the numerators equal to each other since the denominators are the same:

$380 - x = 50$

Step 6: Isolate the variable $x$ by subtracting 380 from both sides:

$-x = 50 - 380$

Step 7: Simplify the right side:

$-x = -330$

Step 8: Finally, multiply both sides by -1 to solve for $x$:

$x = 330$

So, the solution to the equation is $x = 330$.
