VashaNatasha [74]

Answer: B. x, in the second equation

Step-by-step explanation:

The given system :

$2x+6y=9...................(1)\\\\3x-12y=15.........................(2)$

To apply the substitution method , first we need to select the best variable and a equation which is easy to simplify.

From the given system equation (2) have all the numbers which are multiples of 3.

Then we divide 3 on both sides of equation (2), we get

$x-4y=5\\\\\Rightarrow\ x=4y+5$

Therefore, the best variable to solve for and from what equation is x, in the second equation.
