Five times the difference of a number and 9 is equal to twice the number plus 15. What is the number?​

The number is 8

Step-by-step explanation:

Let the number be x

5x - 9 = 2x + 15

5x - 2x = 15 + 9

3x = 24

x = 24/3

x = 8

The number is 20

Step-by-step explanation:

Five times the difference of a number and 9

5(x-9)

is equal to twice the number plus 15.

=2x+15

5(x-9)=2x+15

Distribute

5x-45 = 2x+15

Subtract 2x from each side

5x-45-2x = 2x+15-2x

3x-45 = 15

Add 45 to each side

3x-45+45 =15+45

3x = 60

Divide by 3

3x/3 = 60/3

x =20
