Answer 1

Ответ:

Пошаговое объяснение:

Если вы все правильно написали то

-2 4/5-3х=-1 1/4

-14/5-3х=-5х/4

56+60х=25х

Х=-56/35

Answer 2

To solve the given equation $-2 \frac{4}{5} - 3x = -1 \frac{1}{4}x$, we'll first convert the mixed numbers to improper fractions and then simplify the equation.

$-2 \frac{4}{5}$ as an improper fraction is $-\frac{14}{5}$.

$-1 \frac{1}{4}$ as an improper fraction is $-\frac{5}{4}$.

The equation becomes:

$-\frac{14}{5} - 3x = -\frac{5}{4}x$

To solve for $x$, we'll first get rid of the fractions. The common denominator for 5 and 4 is 20. Multiply every term by 20 to clear the fractions:

$20 \times \left(-\frac{14}{5}\right) - 20 \times (3x) = 20 \times \left(-\frac{5}{4}x\right)$

Simplifying, we get:

$-56 - 60x = -25x$

Now, let's isolate the $x$ terms on one side and the constant term on the other side:

$-60x + 25x = 56$

$-35x = 56$

Divide by -35 to solve for $x$:

$x = \frac{56}{-35}$

Simplifying the fraction, we get:

$x = -\frac{8}{5}$
