Question

Valus of m is :m+2m-6= -12+2m

Answer 1

M + 2m - 6 = -12 + 2m
3m - 6 = -12 + 2m
      +6     +6
--------------------------------
3m = -6 + 2m
 -2m       -2m
-----------------------
1m = -6
/1      /1

m = -6

Answer 2

To find the value of the variable m;

m + 2m - 6 = -12 + 2m
3m - 6 = -12 + 2m (combined like terms)
3m - 2m - 6 = -12 + 2m - 2m (subtracted 2m on both sides)
m - 6 + 6 = -12 + 6 ( added 6 on both sides)
m = -6 
Hope this helps :)
