Slogan
• Algebra makes the simplest things complicated , and the complicated things simple .
Problem
• Matt and Ming are selling fruit for a school fundraiser. Costumers can buy small boxes of oranges and large boxes of oranges. Matt sold 3 small boxes and 14 large boxes of oranges for a total of \$203. Ming sold 11 small boxes of oranges and 11 large boxes of oranges for a total of \$220. Find the cost each of the one small box of oranges and one large box of oranges .
Elimination
• -11(3x+14=203 11y+11(13)=220
• -33y-154x=2233 11y+143=220
• 33y + 33x=660 -143 -143
• -121x=1573 11y=77
• x=13 y=7
Substitution
• 11x+14y=220
• 11
