The image contains mathematical operations and algebraic expressions that need to be solved. Let's break down the questions:

Question 1: Hitunglah hasil operasi aljabar berikut!

Solve the following algebraic operations:

a) $\frac{3}{2x} \times \frac{2x}{3}$

b) $\frac{y-5}{y} \times \frac{2+3y}{y-3}$

c) $\frac{a^3b^2}{a^5b}$

d) $\frac{1}{x+y} \times \frac{3}{x-y}$

Question 2: Tunjukkan bahwa $x - 1$ ekuivalen dengan $\frac{1}{2} (2x - 2)$

Let me start by solving these algebraic expressions. Would you like a detailed solution for each of them?
