Solve the equation graphically 2x+y=6. 2x-y=2
1 answer:
Answer:
x=2 and y = 2
Step-by-step explanation:
Im going to use GeoGebra for graphing the 2 lines. I always find it helpful to move y to side of the equation and the rest of the equation to another side. This is the slope intercept equation by the way. We get our equations as y = -2x+6 and y= 2x-2.
You can find that the common point is (2,2) between the lines.
