The intersection points of both the equations are the solutions

From the graph the points are

  • (6,10)
  • (-2,-6)

Hence

x=-2 and x=6 are the solutions

Answer:

x= -2 and x = 6

Explanation:

The solutions are where the two graphs intersect

x=6, y= 10 is one point

x=-2 and y = -6 is the other point
