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)


What is 5f-3g-7f 3f-4g?

Well, let's take a moment to appreciate these lovely variables, f and g. To simplify this expression, we can combine like terms. So, when we combine the terms with f, we get 5f - 7f + 3f, which simplifies to f. And when we combine the terms with g, we get -3g - 4g, which simplifies to -7g. So, the simplified expression is f - 7g. Remember, there are no mistakes in math, just happy little accidents.

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.
