Define a variable ** Let's say Sabrina has p number of pencils.
How many pencils does Justin have? ** If Justin has 8 more than twice as many pencils as Sabrina, he has 2*p + 8 = 2p+8
How many pencils do Justin and Sabrina have together? ** Together, Justin and Sabrina has p +(2p+8)=50
Simplify ** This is equal to 3p=50-8
Simplify ** 3p=42
How many pencils does Sabrina have? ** The number of pencils that Sabrina has is p=42/3
How many pencils does Sabrina have? ** Sabrina has p=<<14=14>>14 pencils
