Verified Answer :

So I guess we are solving for x here :)
So here is my work...
a=2x+6xz
Basically I think it would be
a=6xz+2x

WAIT WAIT NO I'M WRONG FORGIVE ME!

It's  x=a/2(1+3z)

Answer:

\(x = \dfrac{ a}{ 2+ 6z}\)

Step-by-step explanation:

given,

      a    =  2 x + 6 x z ..........................................(1)

to find the value of x take common from Left hand side of Equation (1)

taking common x

      a    =  ( 2  + 6  z ) x ..........................................(2)

dividing both side by ( 2  + 6  z ) in equation (2) we get

   \(x = \dfrac{ a}{ 2+ 6z}\)

hence, the answer is \(x = \dfrac{ a}{ 2+ 6z}\)
