Like Terms and Variables
Start by collecting like terms...
To simplify an equation is to combine like terms, but you do not solve it for example: simplify 3X+4-X-6 2X-2
You combine like terms.
You add (or subtract) like terms. This will reduce the number of terms in the expression and that is the extent of simplification that you can achieve using this process.
They are used to simplify expressions by helping to reduce the numbers that there is
There are no like terms here.
3b-4-6b-5
When you have an expression you have to simplify by eliminating all grouping symbols and combining like terms.
