Answer 1

Ответ:  -15.

Пошаговое объяснение:

Найдем корень первого уравнения:

3х+2=17

х=(17-2)/3=15/3=5

Уравнения равносильны, если их корни равны.

Подставляем наш корень во второе уравнение.

5+к=-10

к=-10-5=-15.

Answer 2

Solving the Equation 3x + 2 = 17 and x - 10

To find the values of x that make the equations 3x + 2 = 17 and x - 10 equivalent, we can solve for x in both equations and compare the results.

First, let's solve the equation 3x + 2 = 17: - Subtract 2 from both sides: 3x = 15 - Divide both sides by 3: x = 5

Now, let's solve the equation x - 10: - Add 10 to both sides: x = 10

The values of x that make the equations 3x + 2 = 17 and x - 10 equivalent are when x = 5.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
