Simplify the expression
Slav-nsk [51]
First you need to combine like terms.

9x + 11y + 13

A coefficient is the number that comes before the variable (which is y).

The coefficient for y is 11.

Constants are the numbers that do not have variables attached to them.

The constant is 13.

Hope this helps!
