Question: 1 / 400

What is the solution to the equation x/4 = 5?

10

15

20

To solve the equation \( \frac{x}{4} = 5 \), start by eliminating the fraction by multiplying both sides of the equation by 4. This step helps isolate \( x \) more easily.

When you multiply both sides by 4, the equation transforms as follows:

\[

4 \cdot \frac{x}{4} = 4 \cdot 5

\]

This simplifies to:

\[

x = 20

\]

Now, since \( x \) equals 20, this confirms that if you substitute \( x \) back into the original equation \( \frac{x}{4} \), you get \( \frac{20}{4} = 5 \), verifying that the solution is accurate.

In this way, the value of 20 satisfies the equation, making it the correct answer. The other values do not satisfy the equation when checked; for instance, substituting 10, 15, or 25 would not yield 5. Thus, 20 is indeed the correct solution to the equation.
