Let

x--------> the number of Saris pencil erasers

y--------> the number of Sams pencil erasers


we know that

[tex] x+y=28\\ x=28-y [/tex]

equation [tex] 1 [/tex]


[tex] x=3y [/tex]

equation [tex] 2 [/tex]

equate equation 1 and equation 2

so

[tex] 28-y=3y\\ 4y=28\\ y=7 [/tex]

[tex] x=3*7\\ x=21 [/tex]

therefore


the answer is

the number of Saris pencil erasers is [tex] 21 [/tex]
