Question

Look at this system of equations. How can the system be changed so that the two equations have equal x-coefficients?

3x + 2y = 12
6x + 3y = 21

A. Multiply both sides of the top equation by 2
B. Divide both sides of the top equation by 2
C. Multiply both sides of the top equation by 3
D. Divide both sides of the top equation by 3

Answer 1

I believe the correct answer from the choices listed above is option A. The system can be changed so that the two equations have equal x-coefficients by multiplying both sides of the top equation by 2 resulting to 6x + 4y = 24. Hope this answers the question.
