Respuesta :

7k + 5 = - 37

Subtract -5 on both sides of the equation.

7k + 5 = - 37
     - 5      - 5

7k = - 42

divide by 7

7k = - 42
 / 7        / 7

k = - 6

So,

7k + 5 = -37

Subtract 5 from both sides.
7k = -42

Divide both sides by 7.
k = -6

Check
7(-6) + 5 = -37
-42 + 5 = -37
-37 = -37 This checks.

S = {-6}
