Answer 1

Х=28 надеюсь я смогла быстро ответить;)

Answer 2

To find the value of the unknown variable (x), we can solve the equation:

(7 - x) / (-21) = 1

To isolate the variable (x), we can multiply both sides of the equation by (-21):

(-21) * [(7 - x) / (-21)] = (-21) * 1

This simplifies to:

7 - x = -21

Now, let's isolate the variable (x) by moving 7 to the other side of the equation:

x = 7 + 21

x = 28

So, the value of the unknown variable (x) is 28.
