Asystem of two equations is shown below. what will you need to multiply the top equation by in order to solve this system using the elimination method?
x+2y=11
6x+4y=34
a.6
b.2
c.-2
d.-4

For this case we have the following system equations:

To use the elimination method we must multiply the first by -2. So:

In this way, if we add the equations, the variable y is eliminated.

-2

Option C

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
