Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

oh right like terms

Answer 6

\(5x-9 = 3x+1\)

add 9 on both sides
\(5x -9+9 = 3x+1+9 \\ 5x =3x+10 \)

did u get this ?

Answer 7

yea i am getting the idea

Answer 8

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

Answer 9

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

Answer 10

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
