sorry, the first question is 12 - 2m = -2m - 18

there is no solution to the first one because if you add 2m to either side it cancels out and makes it 0m=30 and you cant divide anything by 0

add 6n to the right side and subtract 18 to the left. you would have -32=16n and divide both sides by 16 and you get -2

subtract 7 from both sides and you get -6x>-42, then divide both sides by -6 and you end up with x<7 if you divide by a negative number you switch the signs

12-2m=-2m-18
+2m +2m
12=0m-18
+18 +18
30/0=m undefined


-6n-14=18+10n
+6n +6n
-14=18+16n
-18 -18
-32=16n
-32/16=n
n=-2

7-6x>-35
-7 -7
-6x>-42
-6/-42
x<7
