If write the algebraic expression that corresponds to three times a number?

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

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.
