Please Determine the value of the number being described. When 10 is subtracted from 3 times the number, what is the result if the number is being divided by 2? What is the number?
Solution: We have number 10 which is subtracted from 3 times the number and the number is divided by 2. let the number be x, then 3 ( x/2 ) - 10 = 0 or, 3 ( x/2 ) = 10 or, x/2 = 10/3 or, x * 3 = 10* 2 or, 3x = 20 ∴ x = 20/3
