Nancy bought 354 short sleeve shirts and 177 long sleeve shirts.
Step-by-step explanation:
Given,
x represents the number of long sleeve shirts
y represents the number of short sleeve shirts
According to given statement;
x+y=531 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
[tex]2y+y=531\\3y=531[/tex]
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{531}{3}\\y=177[/tex]
Putting y=177 in Eqn 2
[tex]x=2(177)\\x=354[/tex]
Nancy bought 354 short sleeve shirts and 177 long sleeve shirts.
