Answer 1

1) 12 (5a - 6 ) = 60a-72
2) 7 (5x -7y-6b) = 35x-49y-42b
3) 568 X 43 - 566 X 43 = 86
4) 417 X 187 + 417 X 213 = 166800
5) 17a - 9a = 8a
6) 34a - a = 33a
7) 69n - n - 18 =68n-18
8) 25x + 37x - 17 - x=62x-17

Answer 2

Simplifying and Solving the Equations

To simplify and solve the given equations, let's go through each equation step by step:

1) 12 + (5a - 6): To simplify this equation, we can combine like terms. The equation becomes 12 + 5a - 6. Simplifying further, we get 5a + 6.

2) 7 + (5x - 7y - 6b): Similarly, we can combine like terms in this equation. The equation becomes 7 + 5x - 7y - 6b.

3) 568X + 43 - 566X + 43: In this equation, we have two terms with X. To simplify, we can combine the terms with X. The equation becomes 568X - 566X + 43 + 43. Simplifying further, we get 2X + 86.

4) 417X + 187 + 417X + 213: Here, we have two terms with X. Combining them, we get 417X + 417X + 187 + 213. Simplifying further, we get 834X + 400.

5) 17a - 9a: In this equation, we have two terms with 'a'. Combining them, we get 17a - 9a. Simplifying further, we get 8a.

6) 34a - a: Similar to the previous equation, we have two terms with 'a'. Combining them, we get 34a - a. Simplifying further, we get 33a.

7) 69n - n - 18: In this equation, we have two terms with 'n'. Combining them, we get 69n - n - 18. Simplifying further, we get 68n - 18.

8) 25x + 37x - 17 - x: Here, we have three terms with 'x'. Combining them, we get 25x + 37x - 17 - x. Simplifying further, we get 61x - 17.

Now, let's summarize the simplified equations:

1) 12 + (5a - 6) simplifies to 5a + 6. 2) 7 + (5x - 7y - 6b) remains as 7 + 5x - 7y - 6b. 3) 568X + 43 - 566X + 43 simplifies to 2X + 86. 4) 417X + 187 + 417X + 213 simplifies to 834X + 400. 5) 17a - 9a simplifies to 8a. 6) 34a - a simplifies to 33a. 7) 69n - n - 18 simplifies to 68n - 18. 8) 25x + 37x - 17 - x simplifies to 61x - 17.
