PLS HELP If x=8 and y=3, what is 4y−x? Enter your answer as a number. If it is a negative number, enter it like this: -42

Step-by-step explanation:

If x = 8

and y = 3

then the solution for the expression will be as the follows

Your answer is 4.

check above link.

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.
