Answer 3

To solve the equation 55x = 820 - 170300 - x = 42×2, let's simplify it step by step:

Step 1: Combine the like terms on the right side of the equation. 55x = 820 - 170300 - x + 42×2

Step 2: Perform the arithmetic operations on the right side. 55x = 820 - 170300 - x + 84

Step 3: Combine the constants on the right side. 55x = -169396 - x

Step 4: Move all the terms containing x to one side of the equation. 55x + x = -169396

Step 5: Combine the x terms on the left side. 56x = -169396

Step 6: Isolate x by dividing both sides by 56. x = -169396 / 56

Step 7: Calculate the value of x. x ≈ -3024.2857

So, the solution to the equation is approximately x ≈ -3024.2857.
