Question

3/9⋅y−4=−13+y/9 хелп плиз

Answer 1

Ответ:

y=-81/2

y=-40,5

Объяснение:

1/3y-4=-13+y/9

3y-36=-117+y

3y-y=-117+36

2y=-81

y=-81/2

Answer 2

To solve the equation $\frac{3}{9} \cdot y - 4 = -13 + \frac{y}{9}$ for $y$, follow these steps:

Step 1: Clear the fractions by multiplying both sides of the equation by the common denominator, which is $9 \times 9 = 81$: $81 \left( \frac{3}{9} \cdot y - 4 \right) = 81 \left( -13 + \frac{y}{9} \right)$

Simplify both sides: $27y - 324 = -117 + y$

Step 2: Move all terms involving $y$ to one side of the equation and constants to the other side: $27y - y = -117 + 324$

Simplify: $26y = 207$

Step 3: Solve for $y$ by dividing both sides by 26: $y = \frac{207}{26}$

Step 4: Simplify the fraction: $y = 7.9615$

So, the solution to the equation is approximately $y = 7.9615$.
