Question

3/7 * y - 12 = -13 + y/7

Answer 1

Объяснение:

$\frac{3}{7} \times y - 12 = - 13 + \frac{y}{7} \\ 3y - 84 = - 91 + y \\ 3y - y = - 91 + 84 \\ 2y = - 91 + 84 \\ 2y = - 7 \\ y = - \frac{7}{2} = - 3 \frac{1}{2} = - 3.5$

Answer 2

3y-84= -91+y

3y-y= -91+84

2y= -7

Ответ: y= -7/2 или y= -7:2

y= -3,5

Answer 3

To solve the equation $\frac{3}{7} \cdot y - 12 = -13 + \frac{y}{7}$ for $y$, you can follow these steps:

1. Clear the fractions by multiplying both sides of the equation by the least common denominator, which is $7$:

   $7 \cdot \left( \frac{3}{7} \cdot y - 12 \right) = 7 \cdot \left( -13 + \frac{y}{7} \right)$

   Simplify both sides.

2. Solve for $y$:

   $3y - 84 = -91 + y$

   Subtract $y$ from both sides:

   $2y - 84 = -91$

   Add $84$ to both sides:

   $2y = -7$

   Divide by $2$:

   $y = -\frac{7}{2}$

So, the solution to the equation is $y = -\frac{7}{2}$.
