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.
