Answer:
I KNOW IT I HAD IT LAST YEAR
Step-by-step explanation:
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
![2y+y=531\\3y=531](https://tex.z-dn.net/?f=2y%2By%3D531%5C%5C3y%3D531)
Dividing both sides by 3
![\frac{3y}{3}=\frac{531}{3}\\y=177](https://tex.z-dn.net/?f=%5Cfrac%7B3y%7D%7B3%7D%3D%5Cfrac%7B531%7D%7B3%7D%5C%5Cy%3D177)
Putting y=177 in Eqn 2
![x=2(177)\\x=354](https://tex.z-dn.net/?f=x%3D2%28177%29%5C%5Cx%3D354)
Nancy bought 354 short sleeve shirts and 177 long sleeve shirts.
