Question 81327
QUESTION:


5m+8=3(m+4)


ANSWER:


5m + 8 = 3( m + 4 )


First remove the parenthesis by multiplying with the term outside the parenthesis.



==> 5m + 8 = 3 * m + 3 * 4



==> 5m + 8 = 3m + 12


Subtract 3m from both sides...



==> 5m + 8 - 3m = 3m + 12 - 3m


==> 5m - 3m + 8 = 3m - 3m + 12



==> 2m + 8 = 12



Subtract 8 from both sides....



==> 2m + 8 - 8 = 12 - 8



==> 2m = 4



Now divide both sides by 2



==> 2m/2 = 4/2



==> m = 2



So the solution of the given equation is,


  m= 2


Hope you found the explanation useful.
