Answer 3

Let's analyze the given equations step by step:

1. 2400:(x-12) = 80

To solve this equation, we need to isolate the variable x. We can start by multiplying both sides of the equation by (x-12):

2400 = 80(x-12)

Next, we can divide both sides by 80:

2400/80 = x-12

Simplifying the left side:

30 = x-12

Now, let's solve for x by adding 12 to both sides:

30 + 12 = x

x = 42

So, the value of x is 42.

2. 2400:(42-12) = 80

In this equation, we substitute x with the value we obtained in the previous step, which is x = 42:

2400:(42-12) = 80

Simplifying the denominator:

2400:(30) = 80

Dividing 2400 by 30:

80 = 80

Therefore, the equation is true. Both sides are equal, confirming the correctness of the calculations.

In summary, the value of x is 42, and the equation 2400:(42-12) = 80 holds true.
