What is 7a 6 simplified?

To simplify the expression 7a - 6, we combine like terms by adding or subtracting coefficients of terms with the same variables. In this case, there are no like terms to combine, so the expression remains as 7a - 6. It cannot be simplified further without additional context or information.


Simplify the variable expression which is 16x- 8-5-6x-4?

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.

Does an expression have an answer?

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)

How do you simplify 8x - 8 - 4x - 3 3x?

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.


What is the answer to this equation -6 n -30?

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".
