Question

Select the correct answer. The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the y-variable, and what is the solution for this system? x + 3y = 42 2x − y = 14 A. Multiply the second equation by -3. The solution is x = 12, y = 9. B. Multiply the second equation by -2. The solution is x = 12, y = 10. C. Multiply the second equation by 2. The solution is x = 15, y = 9. D. Multiply the second equation by 3. The solution is x = 12, y = 10.(help i will give brainliest.)

Answer 1

Answer:

c

Step-by-step explanation:

Multiply the second equation by 2. The solution is x = 15, y = 9.

Answer 2

Answer: D

Step-by-step explanation:

It’s 3y so to get rid of the y variable you divide by what number is in front of it
