The variable x represents the number of long-sleeve shirts Nancy bought and the variable y represents the number of short-sleeve shirts she bought.

Nancy bought 531 shirts for her business. She bought 2 times as many short-sleeve shirts as long-sleeve shirts.

How many of each type of shirt did she buy?

Which system of equations models this problem?

The correct answer is: x+2y=531, y=2x
Answered by I Know
actually the correct system would be

x+y = 531
y = 2x

solving:
using sub
x +2x = 531
3x = 531
x = 177, and y = 354

twice as many y's as x's ? YES
sum of x and y = 177+354 =531, all is good here
