Let x be the number.
Set up an equation:
2x - 2/3x = 20
Simplify:
1 1/3x = 20
Divide both sides by 1 1/3
X = 15
The number is 15
I can’t see any image
Can you please provide the image so i can help
Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5
