Answer 2

To solve for the value of x in the equation:

(72100 - 5210) - (5x + 90) = 23100 + 42 - 10

You can follow these steps:

1. Calculate the values on both sides of the equation separately:

   Left side: (72100 - 5210) - (5x + 90) = (7200 - 520) - (5x + 90) = 6680 - (5*x + 90)

   Right side: 23*100 + 42 - 10 = 2300 + 42 - 10 = 2332 - 10 = 2322

2. Now, rewrite the equation with the simplified values:

   6680 - (5*x + 90) = 2322

3. To isolate the variable x, start by moving the -90 on the left side to the right side by adding 90 to both sides of the equation:

   6680 - (5*x + 90) + 90 = 2322 + 90

   This simplifies to:

   6680 - 5*x = 2412

4. Next, isolate the -5*x term by subtracting 6680 from both sides:

   6680 - 5*x - 6680 = 2412 - 6680

   -5*x = -4268

5. Finally, solve for x by dividing both sides by -5:

   (-5*x) / (-5) = (-4268) / (-5)

   x = 853.6

So, the solution to the equation is x = 853.6.
