Question

15*х 45+15 (60+24):х 28

Answer 1

15х=45+15

15х=60

Х=4

‾‾‾‾‾

15*4=45+15

60=60

(60+24):х=28

84:х=28

Х=84:28

Х=3

‾‾‾‾‾

(60+24):3=28

28=28

Answer 2

It looks like you've provided a mathematical expression that involves some calculations. Let's break it down step by step:

Expression: 15 * x + 45 + 15 * (60 + 24) / x * 28

1. Start with the innermost parentheses: 60 + 24 = 84

2. Multiply 15 by the result of the inner parentheses: 15 * 84 = 1260

3. Divide the result by x: 1260 / x

4. Multiply the result by 28: 28 * (1260 / x) = 35280 / x

5. Now add the first two terms of the expression: 15 * x + 45

6. Finally, combine the two results: (15 * x + 45) + (35280 / x)

So, the simplified expression is: 15x + 45 + 35280 / x
