Looks like we have a multivariable equation.
But don't worry, I can help! :)
When you are doing an equation like this, we want all the numbers (without variables) on one side and numbers with variables on the other side to begin with.
So let's subtract 5m from each side. When you subtract 5m from the left side you cancel out the whole term. But when we subtract 5m from the right side, you get -1m or -m (4m - 5m).
Alright, so far we have this :
-1 = -m + 5 OR -1 = -1m + 5
Now what we need to do after is get rid of any extra numbers (without variables) on the side of the number (with a variable).
Subtract -5 from each side to cancel out the positive 5 on the right. And do the same thing to the left.
So we end up with -6 = -1m.
Now we need to get the variable, "m," by itself, so we divide the number next to, "m," by itself to get, "m," by itself.
So divide each side by -1. Divide -1m by -1 to get, "m." And divide -6 by -1 to get 6 (a negative divided by a negative is a positive).
Your Final answer is :
m = 6
