45-m/30 = 165
*30 *30
-----------
45-m = 4950
-45 -45
-----------
-m = 4905
divide by -1 on both sides
m= -4905
*30 *30
-----------
45-m = 4950
-45 -45
-----------
-m = 4905
divide by -1 on both sides
m= -4905

so first you multiply both sides by 30
then you subtract 45 from both sides
and then divide by -1 on both sides

45-m/30 = 165
Multiply both sides by 30
45-m = 4 950
Subtract 45 from both sides
-m = 4905
M cannot be negative so change signs on both sides.
m = -4905
Now if you plug in what m equals you should get 165
45-(-4905)/30=165
Multiply both sides by 30
45-m = 4 950
Subtract 45 from both sides
-m = 4905
M cannot be negative so change signs on both sides.
m = -4905
Now if you plug in what m equals you should get 165
45-(-4905)/30=165

One way to check your answer is to plug what m equals into your original equation
(45 - 6300)/30 = 165
That is a false statement.
(45 - 6300)/30 = 165
That is a false statement.
