2. Which variable will eliminate? *
3x +6y=27
-3x+8y= 1
2 answers:
Answer:
the x variable
Step-by-step explanation:
Given the 2 equations
3x + 6y = 27 → (1)
- 3x + 8y = 1 → (2)
Since the signs of the coefficients of x are opposite, then adding them will eliminate the x- term, that is
Add (1) and (2) term by term
0 + 14y = 28
14y = 28 ( divide both sides by 14 )
y = 2
Then substitute y = 2 into either equation for corresponding value of x
