Answer:
The missing value in the solution to 
the equation will be: 
Step-by-step explanation:
Given the equation

As the value of y = -2 is given.
so substituting the value y = -2 in the equation to find the missing value

switch the sides








Therefore, the missing value in the solution to 
the equation will be:
