The equations have equal x-coefficients is to A. Multiply both sides of the top equation by 2.
Multiplying both sides of the top equation by 2 results in:
8x + 4y = 8
This makes the x-coefficients equal in both equations, as they are both now 8x.
Option B would not work, as dividing both sides of the top equation by 4 would result in an x-coefficient of 1x in the first equation and 8x in the second equation.
Option C would also not work, as dividing both sides of the top equation by 2 would result in an x-coefficient of 2x in the first equation and 8x in the second equation.
Option D would work, as multiplying both sides of the top equation by 4 would result in an x-coefficient of 8x in both equations. However, option A is the simplest and most direct way to achieve the desired result.
Therefore, the correct answer is A. Multiply both sides of the top equation by 2.
