Question

If 2/3 of a certain number is subtracted from twice the number, the result is 20. Find the number.​

Answer 1

15

Explanation:

Let x be that number.

2/3 of x subtracted from twice of x is 20.

2x - 2/3x = 20

Solve for x.

Combine like terms.

4/3x = 20

Multiply both sides by 3/4

x = 60/4

x = 15

The number is 15.

Answer 2

`\boxed{x = 15}`

Explanation:

Let the number be x

Condition:

`2x - (2)/(3) x = 20`

Multiplying 3 to both sides

=> 3(2x) - 2x = 3(20)

=> 6x - 2x = 60

=> 4x = 60

Dividing both sides by 4

=> x = 15
