yes it is so how are you guys doing. im good
To simplify a variable expression by evaluating its numerical part, first identify and calculate any numerical constants or coefficients present in the expression. Combine these numerical values through addition, subtraction, multiplication, or division as appropriate. After simplifying the numerical part, rewrite the expression by maintaining the variable components, resulting in a more concise and easier-to-understand form. For example, in the expression 3x + 5x, the numerical part (3 + 5) simplifies to 8, resulting in 8x.
A numerical expression is ' 2 + 3' A numerical equation is ' 2 + 3 = 5'.
Simplify !
The first step is to substitute the given values into the variable expression. This involves replacing each variable with its corresponding numerical value to simplify the expression. Once the values are substituted, you can then perform any necessary arithmetic operations to evaluate the expression.
The expression (-8u - 1.68) is not an equation, so it doesn't have a specific numerical answer without a value for (u). If you're looking to simplify or evaluate it, you would need to substitute a value for (u). Otherwise, it remains as is: (-8u - 1.68).

To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.
After multiplying or dividing two rational expressions it is sometimes possible to simplify the resulting expression.
