Start by simplifying the equation: \( \frac{9}{2} + \frac{1}{4}(x+2) = \frac{3}{4}x \).
Distribute \( \frac{1}{4} \) to both terms inside the parentheses: \( \frac{1}{4}x + \frac{1}{2} \).
Combine like terms on the left side: \( \frac{9}{2} + \frac{1}{2} = 5 \), so the equation becomes \( 5 + \frac{1}{4}x = \frac{3}{4}x \).
Subtract \( \frac{1}{4}x \) from both sides to isolate terms involving \( x \): \( 5 = \frac{3}{4}x - \frac{1}{4}x \).
Simplify the right side: \( \frac{3}{4}x - \frac{1}{4}x = \frac{1}{2}x \), leading to \( 5 = \frac{1}{2}x \).
