Answer:
[tex]x = \dfrac{ a}{ 2+ 6z}[/tex]
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
[tex]x = \dfrac{ a}{ 2+ 6z}[/tex]
hence, the answer is [tex]x = \dfrac{ a}{ 2+ 6z}[/tex]
