how to combine like and unlike terms
Like Terms: These are those terms that contain the same variables raised to the same power.
2x + 3y + 15 + 3x
Terms 2x and 3x are like terms so when we solve this sum we write:
2x + 3x +3y + 15
or 5x + 3y + 15
Terms are like terms so when we solve this sum we write:
Unlike Terms:These terms cannot be combined.
2x + 3y + 15z
Terms are unlike terms so we can't combine them.
