what is 3x - 4
Understand the Problem
The question is asking for the expression 3x - 4, which is a linear expression in terms of the variable x. It could also imply a need for simplification or evaluation at a specific value of x.
Answer
$3x - 4$
Answer for screen readers
The final expression is $3x - 4$.
Steps to Solve
-
Identifying the Expression We start with the expression given in the problem: $3x - 4$.
-
Substituting a Value (if needed) If the next step requires evaluation, we would substitute a specific value of $x$. For example, if $x = 2$, we calculate: $$ 3(2) - 4 $$
-
Performing the Calculation Now, we perform the calculation. Continuing from the substitution example: $$ 3(2) - 4 = 6 - 4 = 2 $$
-
Final Result If no specific values are given to evaluate, the expression remains as is: $3x - 4$.
The final expression is $3x - 4$.
More Information
The expression $3x - 4$ represents a linear function, which could show the relationship between $x$ and its output. If further values for $x$ were specified, we could evaluate this expression to find the specific output.
Tips
- Not simplifying an expression if possible; ensure to reduce to simplest form if applicable.
- Forgetting to substitute the value of $x$ before calculating if an evaluation is required.
