Tennis balls are sold in packages of 3. Golf balls are sold in packages of 12. A sporting goods store orders 15 packages of balls. The total number of balls is 126.
The system of linear equations g + t = 15, 12g + 3t = 126 represents the scenario where g is the number of packages of golf balls and t is the number of packages of tennis balls.
The system of linear equations is graphed below.

anonymous · Answer

i just solved it o-o xD sorry it took so long, i went the long way because the short way didnt work.

anonymous · Answer

So its kinda easy to solve for the variables and all cause all i have to do is plug each answer into the equation and whichever one works is my answer :D

anonymous · Answer
