To determine the solution that makes the equation \( \frac{x}{4} = 2 + 4 \) true, we first simplify the right side of the equation.
Calculating the right side: \[ 2 + 4 = 6 \]
So, we rewrite the equation as: \[ \frac{x}{4} = 6 \]
Next, we solve for \( x \) by multiplying both sides of the equation by 4: \[ x = 6 \times 4 \] \[ x = 24 \]
Therefore, the solution that makes the equation true is \( x = 24 \).
