What is the solution to the system: 9x+3y=24 2y+4x=8

The solution is x = 4 and y = -4

Step-by-step explanation:

(9x + 3y = 24)-2  

(4x + 2y = 8)3

-18x - 6y = -48

12x + 6y = 24

-6x = -24

x = 4

Plug this into one of the equations

2y+4(4)=8

2y + 16 = 8

     - 16     - 16

2y = -8

y = -4

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
