To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry d

Oksanka [162]

Answer:

"because the graphs of the two equations overlap each other"

Step-by-step explanation:

If he graphs both equations on the graphing calculator and it shows only one line this can mean only one thing:

<em>Both linear equations are the same</em>

An example of this is

x+y=2

2x+2x=4

If you simplify the second equation by dividing everything by 2 you get the same equation as the first one

This means the answer would be "because the graphs of the two equations overlap each other"
