Answer:
m = - 16
Step-by-step explanation:
Given
m + 4 = - 12 ( isolate m on the left side by subtracting 4 from both sides )
m = - 12 - 4 = - 16
Answer: The correct answer is: " -16 " .

Step-by-step explanation:
_______________________________________________
We are given the equation:
→ m + 4 = - 12 ;
We are to solve for the value of "m" ;
Let us solve for "m" ; by subtracting "4" from each side of the equation;
to isolate "m" on one side of the equation; & to solve for "m" ;
→ m + 4 - 4 = -12 - 4 ;
to get:
→ " m = - 16 " ;

→ which is our answer.

Let us check our answer; by plugging in "-16" for "m" ; in the original equation; to see if the original equation holds true when "m = -16 " ;
→ " m + 4 = -12 " ;
Substitute "-16" ; for "m" ;
→ " (-16) + 4 =? -12 ?? " ;
→ " -12 =? -12 ?? " ; Yes!
→ " -12 = -12 " . Yes!
