It looks like you've provided a set of equations. If you need help solving them, I can certainly assist you. Here are the solutions to the equations you've provided:

1. 257 - x + 124 = 149 -x = -232 x = 232

2. 165 - (y + 112) = 37 -y - 112 = -128 -y = -16 y = 16

3. 44 + (a - 85) = 105 a - 85 = 105 - 44 a - 85 = 61 a = 61 + 85 a = 146

4. x - 16 = 72 x = 72 + 16 x = 88

5. 13 * (x - 12) = 104 13x - 156 = 104 13x = 260 x = 260 / 13 x = 20

6. (27 + x) / 5 = 18 27 + x = 18 * 5 27 + x = 90 x = 90 - 27 x = 63

7. 5x + 12 = 87 5x = 87 - 12 5x = 75 x = 75 / 5 x = 15

8. 18 * (x + 15) = 306 18x + 270 = 306 18x = 306 - 270 18x = 36 x = 36 / 18 x = 2

9. (93 - x) / 6 = 15 93 - x = 15 * 6 93 - x = 90 -x = 90 - 93 x = 3

These are the solutions to the given equations. If you have any further questions or need more assistance, feel free to ask!
