In August, Jake found a watermelon in his garden that weighed 3 1/4 pounds. Two weeks later he found a second watermelon that weighed 3 times that amount. How much did the second watermelon weigh?

it just depends on which form you need or want but

3 1/4×3

ps click the picture to see the whole thing

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.
