To determine which equation Kelia is solving that leads her to multiply both sides of the equation by 4, we need to look for an equation where the variable \( x \) is divided by 4 (for example, in the form \( \frac{x}{4} \)).
Let's examine each option:
-
\( 6 + \frac{x}{4} = 1 \)
Here, multiplying both sides by 4 would allow her to eliminate the fraction. This fits the step she would take. -
\( 4 + 6x = 1 \)
In this equation, multiplying by 4 wouldn't simplify it effectively related to \( x \). -
\( 6 + 4x = 1 \)
Similar to the previous one, multiplying by 4 wouldn't have a direct simplification regarding \( x \). -
\( 4 + \frac{x}{6} = 1 \)
This has \( x \) divided by 6, not 4.
Since the only equation that includes \( \frac{x}{4} \) is the first one:
The correct answer is: 6 + \(\frac{x}{4}\) = 1.
