Answer 1

Ответ:

x=-1 3/17

Пошаговое объяснение:

3/5x+1/4x+4/7=-3/7    

84x+35x+80=-60

119x+80=-60

119x=-60-80

119x=-140

x=-20/17

-20/17=-1 3/17

Answer 2

To solve for x in the equation:

$-\frac{3}{5}x + \frac{1}{4}x + \frac{4}{7} = -\frac{3}{7}$,

you can combine the x terms on the left side of the equation and then isolate x. Here's the step-by-step solution:

Step 1: Combine the x terms on the left side: $-\frac{3}{5}x + \frac{1}{4}x = -\frac{3}{7} - \frac{4}{7}$, $-\frac{12}{20}x + \frac{5}{20}x = -\frac{7}{7}$, $-\frac{7}{20}x = -1$.

Step 2: Solve for x by isolating it: $x = \frac{-1}{-\frac{7}{20}}$, $x = \frac{-1}{-\frac{7}{20}} \cdot \frac{20}{1}$, $x = \frac{20}{7}$.

So, the solution to the equation is $x = \frac{20}{7}$.
