Question

4)21/53=220/у+300????????????????????????????????​

Answer 1

Ответ:

(-11660/15879)

Пошаговое объяснение:

(-220/x)=300-21/53

(-220/x)=15879/53

-11660=15879x

15879x=-11660

x=(-11660/15879)

Answer 2

To solve the equation, let's first simplify it:

21/53 = 220/у + 300

To eliminate the fractions, we can multiply both sides of the equation by the denominators:

(21/53) * 53 = (220/у + 300) * 53

Canceling out the denominators, we get:

21 = 220/у * 53 + 300 * 53

Now, let's simplify the right side of the equation:

21 = 11660/у + 15900

To isolate the term with у, we can subtract 15900 from both sides:

21 - 15900 = 11660/у + 15900 - 15900

-15879 = 11660/у

To get rid of the fraction, we can multiply both sides by у:

-15879 * у = 11660

Now, we can solve for у by dividing both sides by -15879:

у = 11660 / -15879

Calculating the division:

у ≈ -0.734
