Answer:
A. 84
Explanation:
Given the equation:
[tex]\frac{x}{4}=21[/tex]
To solve for x, multiply both sides of the equation by 4.
[tex]\begin{gathered} \frac{x}{4}\times4=21\times4 \\ x\times\frac{4}{4}=84 \\ x\times1=84 \\ \implies x=84 \end{gathered}[/tex]
The value of x is 84.
Option A is correct.
