Question

3/5⋅y−9=−16+y/5. y=?

Answer 1

Ответ:

3y/5-9=-16+y/5(умножаем обе части уравнения на 5)

3y-9•5=-16•5+y

3y-45=-80+y

2y=-35

y=-17,5

Answer 2

To solve for y in the equation $\frac{3}{5}y - 9 = -16 + \frac{y}{5}$, you can follow these steps:

1. First, eliminate fractions by multiplying both sides of the equation by 5 to get rid of the denominators:

   $5 \cdot \left(\frac{3}{5}y - 9\right) = 5 \cdot \left(-16 + \frac{y}{5}\right)$

   This simplifies to:

   $3y - 45 = -80 + y$

2. Next, isolate the variable y on one side of the equation. You can do this by moving the terms containing y to one side and the constants to the other side. Let's move the terms with y to the left side by subtracting y from both sides:

   $3y - y = -80 + 45$

   This simplifies to:

   $2y = -35$

3. Finally, solve for y by dividing both sides by 2:

   $y = \frac{-35}{2}$

So, the solution for y is $y = -\frac{35}{2}$, which can also be expressed as $y = -17.5$.
