X=75

Answer 2

Problem Analysis

To solve this problem, we can set up an equation based on the given information. Let's denote the initial amount of money Amir had as 'x'. According to the problem, Amir spent half of his money on an album, so he had 'x/2' left. Then, his mother gave him 130 tenge, and his total amount became 205 tenge. We can express this information in the following equation:

x/2 + 130 = 205

Solving the Equation

To solve this equation, we can start by isolating the variable 'x' on one side of the equation. Here are the steps:

1. Subtract 130 from both sides of the equation: x/2 = 205 - 130

2. Simplify the right side of the equation: x/2 = 75

3. Multiply both sides of the equation by 2 to eliminate the fraction: 2 * (x/2) = 2 * 75

4. Simplify the left side of the equation: x = 150

Answer

Therefore, Amir initially had 150 tenge.
