Nancy bought 177 long sleeve and 354 short sleeve shirts.
{x+y=531, y=2x} represents the system of equations for this problem.
Step-by-step explanation:
Let,
x be the long sleeve shirts
y be the short sleeve shirts
Total shirts bought = 531
According to given statement;
x+y=531 Eqn 1
y = 2x Eqn 2
Putting value of y from Eqn 2 in Eqn 1;
Dividing both sides by 3;
Putting x=177 in Eqn 2
