You combine like terms.
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

It is: 4k-10+7-7k combines to -3k-3
An algebric expression can have any number of terms.
-k + 3k = 2k
3k + 1

When they have the same variable.
You combine like terms.
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
When you have an algebraic expression, the term is "reducing" the expression when you write the expression in fewer terms or smaller multiples.
12t + 15
A mathematical expression does not have an answer, if it is algebraic and all of the terms are unlike. For example, x+7y does not have an answer because there are no definite solutions, and there is no possibility to combine like terms. However, the expression 2x+7y+3x does have an answer, but the solution is merely the combination of like terms. (5x+7y)
Combine like terms to give 3n + 2
To simplify expression 5x + 9 - 7x - 11, you can combine the x terms (5x - 7x) to get -2x, and combine the constant terms (9 - 11) to get -2. Therefore, the simplified expression is -2x - 2.
