Let's solve each part of the equation separately:

First, distribute the 2 on the left side:

12800 + 2x = 4002

Subtract 12800 from both sides:

2x = 4002 - 12800
2x = -8798

Now, divide both sides by 2 to solve for x:

x = -4399

First, solve the parentheses:

10 * 11 = 110

Now, multiply 4002 by 110:

4002 * 110 = 440220

Therefore, the solution to the equation is x = -4399 and 4002 (10 11) = 440220.
