9m - 4 = -18 + 2m
First, we transfer 2m to the other side
and change operation from positive to negative. We also do the same for -4 and
change operation from negative to positive in order to solve this equation.
9m - 2m =
-18 + 4
Next we simply
subtract and add from left to right, respectively.
7m = -14
Then, we can now find
m by dividing both sides with 7…
7m/7 =
-14/7
We’ve arrived at the answer!
m = -2
Checking:
9(-2) - 4
= -18 + 2(-2)
-18 - 4 =
-18 - 4
-14 = -14
I hope
this helps. :)
