So to rewrite it so that we can find the side, we just need to isolate the a variable.

So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be 
M + 2m - 6 = -12 + 2m
3m - 6 = -12 + 2m
+6 +6

/1 /1
m = -6
B) The system of equations has a solution
