The point of intersection of two equations

(x,y) = (4,4)

Step-by-step explanation:

Explanation:-

Given that the system of equations

       x + y=8 ..(i)

    x + 4y = 20 ..(ii)

Solving (i) and (ii) equations , we get

     x +  y   = 8

    x + 4y = 20

 -      -        -    

   0 -3y =  -12                    

         y = 4

Substitute    y = 4 in equation (i)

             x + y=8

             x +4 =8

               x = 8-4 = 4

The point of intersection of two equations

(x,y) = (4,4)

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
