Answer:

[tex]\boxed{x = 15}[/tex]

Step-by-step explanation:

Let the number be x

Condition:

[tex]2x - \frac{2}{3} x = 20[/tex]

Multiplying 3 to both sides

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

=> 6x - 2x = 60

=> 4x = 60

Dividing both sides by 4

=> x = 15

Answer:

15

Step-by-step 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.
