Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation 
-----> equation 
Substitute equation
in equation 
![[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7](https://tex.z-dn.net/?f=%20%5B3y%5D%2By%3D28%5C%5C%204y%3D28%5C%5C%20y%3D28%2F4%5C%5C%20y%3D7%20)
find the value of x

therefore
the answer is
Sari has
erasers
