Determine whether the given value is a solution of the equation. YES OR NO(Example 1)
1. 23 = x - 9; x = 14 NO (14 - 9 = 5, not 23)
2. n __ 13 = 4; n = 52
3. 14 + x = 46; x = 32 YES (14 + 32 = 46. Correct !)
4. 17y = 85; y = 5 YES (17*5 = 85. Correct !)
5. 25 = k _ 5 ; k = 5
6. 2.5n = 45; n = 18 YES (2.5*18 = 45. Correct !)
7. 21 = m + 9; m = 11 NO (11 + 9 = 20, not 21)
8. 21 - h = 15; h = 6 YES (21 - 6 = 15. Correct !)
9. d - 4 = 19; d = 15 NO (15 - 4 = 11, not 19)
10. 5 + x = 47; x = 52 NO (5 + 52 = 57, not 47)
11. w - 9 = 0; w = 9 YES (9 - 9 = 0. Correct !)
12. 5q = 31; q = 13 NO (5*13 = 65, not 31)
13. Each floor of a hotel has r rooms. On 8 floors, there are a total of 256 rooms. Write an equation to represent this situation,
8r = 256.
