For the following system if you isolated X in the second equation to use the substitution method what expression would you subst

Anestetic [448]

Option A. зу + 12 is the right answer

Step-by-step explanation:

The substitution method consists of finding the value of a variable from one equation and then putting it into another equation to find the value of other variable.

Given equations are:

$2x+y=8\\-x-3y=-12$

We have to isolate x in the 2nd equation

$-x-3y=-12$

Multiplying equation by -1

$x+3y=12$

Subtracting 3y from both sides

$x+3y-3y=12+3y\\x=12+3y$

Hence,

Option A. зу + 12 is the right answer
