To simplify the expression 8x - 8 - 4x - 3 - 3x, first combine like terms. Start by combining the x terms: 8x - 4x - 3x = x. Then, combine the constant terms: -8 - 3 = -11. Therefore, the simplified expression is x - 11.
Combine like terms to give 3n + 2
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
To simplify the expression 16x - 8 - 5 - 6x - 4, first combine like terms. Combine the x terms by subtracting 6x from 16x to get 10x. Then, combine the constants by adding -8, -5, and -4 to get -17. Therefore, the simplified expression is 10x - 17.

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)

To simplify the expression 8x - 8 - 4x - 3 - 3x, first combine like terms. Start by combining the x terms: 8x - 4x - 3x = x. Then, combine the constant terms: -8 - 3 = -11. Therefore, the simplified expression is x - 11.
To find the answer to the expression 7n - 2 - 3n + 4, you first simplify by combining like terms. Combine the 7n and -3n terms to get 4n. Then, combine the -2 and +4 terms to get +2. Therefore, the final answer is 4n + 2.
Just to get you straight, that is actually an expression. Equations have equal signs in them. Just so you know. Anyway, it just so happens that this expression (-6n - 30) is already simplified. There are no like terms to combine there, since 30 does not have an "n".
