Algebraic Expression - simplify

To simplify an algebraic expression that consists of both like and unlike terms, it might be helpful to first move the like terms together. (When moving the terms, we must remember to move the + or – attached in front of them).

For example,

3x + 2y – 2x + 6

= 3x– 2x + 2y + 6

= (3 – 2)x + 2y + 6

= x + 2y + 6

Example:

Simplify 3x + 2a – 4x

Solution:

3x + 2a – 4x

=3x– 4x + 2a

= (3 – 4)x + 2a

= –x + 2a
