**Quidditch**, Monday, September 15, 2008 at 8:31pmFor 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.

That gives:

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

2

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.

**Ms. Sue**, Monday, September 15, 2008 at 8:54pmGood. I just found that I can't add. Of course 36 + 7 = 43.

Sorry
