Question

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

Answer 1

so the given equation is
`(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


`(1)/(2)`m - 4 ( + 4 ) = 5 ( + 4 )
- 4 and + 4 cancels out in the left hand side

We are left with

`(1)/(2)`m = 9

To find the value of m, we should divide each side by
`(1)/(2)`
(diving by a fraction can also be done by multiplying the reciprocal)

`(1)/(2)`m = 9 ÷
`(1)/(2)`

`(1)/(2) and (1)/(2)` cancels out

m = 18

Answer 2

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!
