For the problem
(4m-7)/2 = 18
To solve for m:
The object is to get a single m on one side of the equation.
1. get rid of the denominator (2) on the left side by multiplying both sides of the equation by 2.
4m-7 = 36
Now add 7 to both sides to get just a term with n on the left.
4m = 43
Now divide both sides by 4 to get the value of m.
m = ?
______ = 18
First, multiply both sides of the equation by 2.
4m - 7 = 36
Next, add 7 to both sides of the equation.
4m - 7 + 7 = 36 + 7
4m = 42
m = 10.5
You can check it by substituting 10.5 for m in your original equation.
m= 10 3/4
thanks, now i understand
Good. I just found that I can't add. Of course 36 + 7 = 43.
