Answer 2

1. 9c - 21 = 9c + 18

We can simplify the equation by subtracting 9c from both sides:

9c - 9c - 21 = 9c - 9c + 18

Simplifying further:

-21 = 18

This is not true, so the equation has no solution.

2. 256x = 1024

To solve for x, we can divide both sides by 256:

256x/256 = 1024/256

Simplifying:

x = 4

Therefore, the solution is x = 4.

3. (35 - x) x = 0

This equation has two solutions: x = 0 and x = 35.

If x = 0, then the left side of the equation becomes (35 - 0) * 0 = 0, which is true.

If x = 35, then the left side of the equation becomes (35 - 35) * 35 = 0, which is also true.

Therefore, the solutions to this equation are x = 0 and x = 35.
