At what value of x do the graphs of the equations below intersect?
Zarrin [17]

Answer:

x = 2

Step-by-step explanation:

  1. You would find a value of y to plug into either of the equations. For example, I chose the equation 2x - y = 6. When I set it equal to y, I got y = 2x - 6
  2. Now that I know what y is equal to, I plugged it into the second equation to get 5x + 10 (2x - 6) = -10
  3. You then would calculate for x.
  4. Your end result should be x = 2, which is the point that the two equations intersect

This works because the two equations are set equal to each other, making them share a common value between them.

You can also plug both of these equations into a graphing calculator, and on the graph select the command to calculate the intersection.

Hope this helped!
