Answer for screen readers
The expression is $4x - 3$.
Steps to Solve
-
Identify the expression The expression provided is $4x - 3$. This is a linear expression featuring the variable $x$.
-
Understand the components The expression consists of two parts: $4x$ which represents four times the value of $x$, and $-3$ which is a constant value subtracted from $4x$.
-
Evaluating the expression To evaluate it at a specific value of $x$, substitute that value into the expression.
For example, if $x = 2$: $$ 4(2) - 3 = 8 - 3 = 5 $$
- General form If a specific value isn't given for $x$, you can express it simply as $4x - 3$, which represents a family of values depending on what $x$ is.
The expression is $4x - 3$.
More Information
This expression represents a linear function where any value of $x$ will yield a corresponding output. Linear expressions can be graphed as straight lines in the coordinate plane.
Tips
- Assuming that an expression needs to be solved for a value without a specific value for $x$. Remember, if no value is provided, you cannot solve for a specific number.
- Misinterpreting the expression as an equation, which requires an equality sign.
