Question

1/2m-4=5 What is the variable 'M' equal to.

Answer 1

Hey there! :D

1/2m-4=5

Add 4 on both sides. 

1/2m=9

Divide both sides by 1/2. 

m=18

I hope this helps!

Answer 2

So the given equation is $\frac{1}{2}$m - 4 = 5

We should add 4 on either side as our first step, in order to find the value of the variable

$\frac{1}{2}$m - 4 ( + 4 ) = 5 ( + 4 )
- 4 and + 4 cancels out in the left hand side

We are left with
$\frac{1}{2}$m = 9

To find the value of m, we should divide each side by $\frac{1}{2}$
(diving by a fraction can also be done by multiplying the reciprocal)
$\frac{1}{2}$m = 9 ÷ $\frac{1}{2}$
$\frac{1}{2} and \frac{1}{2}$  cancels out

m = 18
