Answer 1

-28(3x+7)-42=14

-28(3х+7)=56

3х+7= -2

3х= -9

Ответ: х= -3.

Answer 2

To solve the equation, we can start by simplifying the left-hand side using the distributive property of multiplication:

-28(3x+7) - 42 = -84x - 196 - 42 = -84x - 238

Now we can rewrite the equation as:

-84x - 238 = 14

To isolate the variable x, we can first add 238 to both sides:

-84x = 252

Then, we can divide both sides by -84:

x = -3

Therefore, the solution to the equation is x = -3.
