Question

two third of a number is equal to 10 less than the number itself ​

Answer 1

Answer:

The number is 30

Step-by-step explanation:

let x be the number,

given that,

(2/3)*x = x-10

2x = 3(x-10)

2x = 3x-30

3x-2x = 30

x = 30

_______________________________________________

verification:

two third of 30 = (2/3)*30 = 20

10 less than 30 = 30-10 = 20

above 2 expressions produce the same result and are equal

hence verified
