Answer for your question

Answer 2

Explanation:

1. let the number be x

then, acc to the question,

3x - 9 = 5x -3

5x -3x = -9 + 3

2x = -6

x = -3

2. let the first multiple be x

and second multiple be x+1

then acc to the question,

x + x+3 = 81

2x + 3 = 81

2x = 78

x= 39

and x+ 3 = 42

3. let the number be x

then acc to the question,

7 + 3x = 25/3

3x = 25/3 - 7

3x = (25 - 21) / 3

3x = 4/3

x = 4/9

4. let the number be x

then, acc to the question,

7x -25 = 45

so, 7x= 45+25 = 70

7x = 70

x = 10
