Answer 2

Solving the Equation

To solve the given equation 7(y - 3) - a(3 - y) + b^2 * (a - 1) - c(1 - a), we can follow the standard steps for solving linear equations.

First, let's simplify the equation step by step.

1. Expand the Terms - Expand the terms within the parentheses and simplify the equation.

The expanded equation is: 7y - 21 - 3a + ay + b^2 * a - b^2 - ac + c

2. Combine Like Terms - Combine the like terms in the equation.

The combined equation is: ay + 7y - 3a + b^2 * a - b^2 - ac + c - 21

3. Rearrange the Terms - Rearrange the terms in the equation to bring similar terms together.

The rearranged equation is: (ay + 7y) + (-3a - ac) + (b^2 * a - b^2 + c) - 21

4. Final Equation - The final equation after rearranging the terms is: (a + 7)y - (3a + ac) + (b^2 * a - b^2 + c) - 21

Conclusion

The equation 7(y - 3) - a(3 - y) + b^2 * (a - 1) - c(1 - a) simplifies to (a + 7)y - (3a + ac) + (b^2 * a - b^2 + c) - 21 after expanding, combining like terms, and rearranging the terms.
