Искренне надеюсь, что ты поймёшь мой подчерк....Если что то не понятно-спрашивай:)

Answer 3

To solve the equation 280 + 20 - 70X - 300 = 160 + 40900 - 1 = 600 - 2003, we need to simplify the right side of the equation and then solve for X.

Let's simplify the right side of the equation step by step:

160 + 40900 - 1 = 600 - 2003

First, let's add the numbers on the right side:

160 + 40900 - 1 = 600 - 2003 = 41059 - 1 = 600 - 2003 = 41058 = 600 - 2003

Now, let's subtract the numbers on the right side:

41058 = 600 - 2003 = 41058 = -1403

Now, let's solve for X by isolating it on one side of the equation:

280 + 20 - 70X - 300 = 41058

First, let's combine like terms on the left side:

280 + 20 - 70X - 300 = 41058 = 300 - 70X = 41058

Next, let's isolate the variable by moving the constants to the other side:

300 - 70X = 41058 = -70X = 41058 - 300 = -70X = 40758

Finally, let's solve for X by dividing both sides of the equation by -70:

-70X = 40758 = X = 40758 / -70 = X ≈ -582.26

Therefore, the solution to the equation 280 + 20 - 70X - 300 = 160 + 40900 - 1 = 600 - 2003 is X ≈ -582.26.
