Answer 2

It looks like you have a set of equations, and you'd like to solve for the variables (x, y, b, c) in each of them. Let's solve these equations one by one:

1. (x - 23) * 14 = 56 To solve for x, first divide both sides by 14: (x - 23) = 56 / 14 (x - 23) = 4

Now, add 23 to both sides to isolate x: x = 4 + 23 x = 27

2. (200 + x) / 12 = 32 To solve for x, first multiply both sides by 12: 200 + x = 32 * 12 200 + x = 384

Now, subtract 200 from both sides to isolate x: x = 384 - 200 x = 184

3. 205 * (y - 27) = 41 To solve for y, first divide both sides by 205: (y - 27) = 41 / 205 (y - 27) = 0.2

Now, add 27 to both sides to isolate y: y = 0.2 + 27 y = 27.2

4. 729 / (c - 15) = 81 To solve for c, first multiply both sides by (c - 15): 729 = 81 * (c - 15)

Now, divide both sides by 81: 9 = c - 15

Now, add 15 to both sides to isolate c: c = 9 + 15 c = 24

5. 89 * (b + 13) = 7120 To solve for b, first divide both sides by 89: (b + 13) = 7120 / 89 (b + 13) = 80

Now, subtract 13 from both sides to isolate b: b = 80 - 13 b = 67

6. 12 * (97 - 2) = 240 This equation is already simplified and doesn't have a variable to solve for. It's just an equation with a numerical result, which is 240.

So, the solutions are:

1. x = 27
2. x = 184
3. y = 27.2
4. c = 24
5. b = 67
6. 12 * (97 - 2) = 240
