9у-3у-7у=-61-72

-у=-133

у=-133:-1

у=133

Answer 2

Solving the Equation

To solve the equation 9(8 + y) - 3y = 7y - 61, we can follow these steps:

1. Distribute the 9 on the left side of the equation. 2. Combine like terms. 3. Solve for y.

Step 1: Distribute the 9

First, distribute the 9 to both terms inside the parentheses: 9 * 8 + 9 * y - 3y = 7y - 61

This simplifies to: 72 + 9y - 3y = 7y - 61

Step 2: Combine Like Terms

Combine the like terms on the left side of the equation: 72 + 6y = 7y - 61

Step 3: Solve for y

Now, let's solve for y: Subtract 6y from both sides: 72 = y - 61

Add 61 to both sides: 133 = y

Conclusion

The solution to the equation 9(8 + y) - 3y = 7y - 61 is y = 133.
