4x - 16 = 20
Understand the Problem
The question is presenting a mathematical equation to solve for the variable x. The equation appears to be incomplete or miswritten, but it involves solving for x in an algebraic expression.
Answer
$x = 9$
Answer for screen readers
The final answer is $x = 9$.
Steps to Solve
- Add 16 to Both Sides
To isolate the term with $x$, we first need to eliminate the constant on the left side. We'll add 16 to both sides of the equation.
$$ 4x - 16 + 16 = 20 + 16 $$
This simplifies to:
$$ 4x = 36 $$
- Divide by 4
Next, we need to solve for $x$ by dividing both sides of the equation by 4.
$$ \frac{4x}{4} = \frac{36}{4} $$
This simplifies to:
$$ x = 9 $$
The final answer is $x = 9$.
More Information
