All 3 sides are given equal
so equate them
$5x-9=3x+1$
can you try to find x from here ?

anonymous · Answer

so I subtract 5x-9=-4? and then 3x+1=4x?

hartnn · Answer

you cannot combine 5x and -9
they are not like terms!

anonymous · Answer

oh right like terms

hartnn · Answer

$5x-9 = 3x+1$

add 9 on both sides
$5x -9+9 = 3x+1+9 \ 5x =3x+10 $

did u get this ?

anonymous · Answer

yea i am getting the idea

hartnn · Answer

now try to subtract 3x from both sides
what do u get ?

anonymous · Answer

hmmm... I would said C.? I think

hartnn · Answer

no...see the steps
$5x =3x +10 

 \ 5x -3x = 3x-3x+10 \ 2x = 10 \ x=5$

see if you get them, ask if any doubts
