2/7m-1/7=3/14

Solve using properties of equality

Answer 1

Greetings!

"Solve:
`2/7m-1/7=3/14`."...

Solve for m.

`2/7m-1/7=3/14`
Add 1/7 to both sides.

`(2/7m-1/7)+1/7=(3/14)+1/7`
Simplify.

`2/7m=(3/14)+1/7`
Find a common denominator.

`2/7m=(3/14)+2/14`

`2/7m=5/14`
Multiply both sides by 7/2.

`(2/7m)*7/2=(5/14)*7/2`
Simplify.

`m=35/28`

`m=5/4`

The variable is equal to 5/4.

Hope this helps.

Answer 2

Add 1/7 to each side.
2/7m=5/14

Multiply both sides by 14
4m=5

Divide both sides by 4
m=5/4

The answer is m=5/4.

Hope this helps!
