Answer 2

It looks like you have three equations involving variables, and you'd like to solve for the variables in each equation. Let's solve each one separately:

1. 400 - k = 40: To solve for k, you need to isolate it on one side of the equation. You can do this by subtracting 40 from both sides:

   400 - k - 40 = 40 - 40 360 - k = 0

   Now, add 'k' to both sides:

   360 - k + k = 0 + k 360 = k

   So, k = 360.

2. 400/m = 40: To solve for m, you need to isolate it on one side of the equation. You can do this by dividing both sides by 40:

   (400/m) / 40 = 40 / 40 10/m = 1

   Now, to solve for 'm,' take the reciprocal of both sides:

   (10/m)^(-1) = 1^(-1) m/10 = 1

   Now, multiply both sides by 10:

   (m/10) * 10 = 1 * 10 m = 10

3. n - 40 = 400: To solve for n, you need to isolate it on one side of the equation. You can do this by adding 40 to both sides:

   n - 40 + 40 = 400 + 40 n = 440

So, the solutions are:

• k = 360
• m = 10
• n = 440
