What are the two primary roles of the pancreas?

The pancreas has both a primary endocrine role and a primary exocrine role. Its primary endocrine role is to produce and release hormones that control blood sugar levels. Its primary exocrine role is to produce digestive enzymes such as amylase, lipase, and trypsin in order to aid in digesting carbohydrates, fats, and proteins, respectively.

### Subject: Algebra

Solve the equation 3x+(8-2)=21 for the variable, x.

Begin by solving the expression inside the parentheses, (8-2). This will simplify the equation to 3x+6=21. Next, subtract 6 from both sides of the equation to begin isolating the variable. This will make the equation 3x=15. Finally, divide both sides of the equation by 3 to complete isolating the variable. This will give the solution, x=5.
