Answer
The value of $x$ is $7$.
Answer for screen readers
The value of $x$ is $7$.
Steps to Solve
-
Identify the equation We start with the equation: $$ x + 4 = 11 $$
-
Isolate the variable x To find $x$, we need to move the constant term (4) to the other side of the equation. We do this by subtracting 4 from both sides: $$ x + 4 - 4 = 11 - 4 $$
-
Simplify the equation After simplifying, we have: $$ x = 11 - 4 $$
-
Calculate the value of x Now, compute the right side: $$ x = 7 $$
The value of $x$ is $7$.
More Information
This is a basic one-step equation where we subtract a constant to isolate the variable. One-step equations are fundamental in algebra and help build skills for more complex equations.
Tips
- Forgetting to perform the same operation on both sides of the equation.
- Incorrectly simplifying the arithmetic on either side (e.g., calculating $11 - 4$ incorrectly).
