sample problem
9b + 3a - a + 6+ 2b + 4
terms would be each number or number plus a variable separated by an operation symbol (+ or -)
like terms would be 9b and 2b, 3a and -a, and 6 and 4
simply add 9b + 2b (which is 11b)
3a-a (which is 2a)
and 6 + 4 (which is 10)
your answer would then be 11b + 2a + 10
hope that helped
There is nothing that you can do when you combine like terms that you cannot do without combining them. Some procedures might be easier, though, if like terms are combined.
Add
To combine like terms, first identify terms that have the same variable raised to the same power. For example, in the expression (3x + 5x), both terms have the variable (x). Add or subtract the coefficients of these like terms; in this case, (3 + 5) equals (8), resulting in (8x). Lastly, ensure that any terms that are not like terms remain unchanged in the expression.
Combine 'like' terms.
To simplify the expression (3x + 2y + 5x - 6y), combine like terms. First, combine the (x) terms: (3x + 5x = 8x). Then, combine the (y) terms: (2y - 6y = -4y). Thus, the simplified expression is (8x - 4y).
To add like terms, find the terms that have the same (or no) variable, and combine the coefficients of the terms. For instance, if you have a+b where a and b are real numbers, you can combine them.

no, combining like terms means combine the terms that are the same 15+x+6+x=28 combine like terms 21+2x=28 2x=7 x=3.5

yes
You can combine like terms - combine the terms that have a "t" in them; separately, combine the terms that don't.

Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.
All multiples of x are like terms, as all multiples of x2 are also like terms. To combine terms is simply to add them up. So if you have an equation such as, 3x2 + 4x2 + 2x + 6x + 10 = 0, you can combine the like terms; the result is 7x2 + 8x +10 = 0.
