Answer 2

Step-by-step explanation:

1. Let the whole number be x.

Then, according to the question :

10 + 3X = 40

=>3X = 40 - 10

=>3X = 30

=>X = 30/3

=>X = 10

Therefore, the number is 10.

2. Let the number be X.

Then, according to the question :

4/5X - 3/4X = 8

=> 16X/20 - 15X/20 = 8

=> X/20 = 8

=> X = 8 × 20

=> X = 160

4. 2 ( X - 1) + 2 ( 3X - 1) = 0

=> 2X - 2 + 6X - 2 = 0

=> 8X - 4 = 0

=> 8X = 4

=> X = 4/8

=> X = 1/2

5. 4 ( X - 1) - ( 2X - 5 ) = 4

=> 4X - 4 - 2X + 5 = 4

=> 2X + 1 = 4

=> 2X = 4 - 1

=> 2X = 3

=> X = 3/2
