Combining+Like+Terms+1Y

The way you combine liek terms is in simpliest terms: Combine the same letters. Example: 3x+2y-3y the way you would solve this probelm is by adding or subtracting the variable(letter) so you would subtract 2y from 3y because it says minus then you will be left with -1 then you add the 3x in and the aswer would be 3x-1y.

Nailah Adam: The trick to combinig like terms is to find the pairs. If 2x+7x+8y the problem and you have to do is combine 2x and 7x while 8y will stay the same. So 9x+8y will be the answer. //This is a video I found that shows you everything you need to know about combining like terms.// You can visit: [|Combining Like Terms] to do it your self. media type="google" key="-4260814615528606900&hl=en&fs=true" width="400" height="326"

3. Some variable simplify cannot be combined.
 * o Always True** o Sometimes True o Never True

Example: Whenver you simplify an equation you must always combine like terms, or it will not work. This picture shows how when solving equations you have to add like terms or until you cant, and thats when you're done collaborators: none

15. Substitution is a method that will allow you to solve for another variable. o True example: 4x+3=15 the x is substituting for the number 3. so it's allowing u to solve for another variable.
