Anne, Barry and Colin share a prize in the ratio 3:4:5. Colin gives 1/3 of his share to a charity.
What fraction of the whole prize does Colin give to the charity?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

sine

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.
