1.	Write the following statemens in symbolic form. (i) A number si doubled and edded to 6, the result is equal to 14 (ii) The sum of a number and three fifth of the number is equal to 24. (iii) Twenty years ago, the age of man was half of his preent age.
Answer» Correct Answer - (i) `2x+6 = 14` (ii) `x + (3x )/(5) = 24` (iii) `x - 20 = (x)/(2)` (i) A number id doubled and added to 6, the result is equal to 14 Let the number be x. Double the number =2x It is added to 6. `rArr2x+6` The result is equal to 14 `rArr2x+6=14` (ii) Let the number be x. `(3)/(5)` of the number `=(3x)/(5)` Given thant `x+(3x)/(5)=24` (iii) Let the present age of the be x years. 20 years ago the ae of the man =(x-20) years Given `x-20=(x)/(2)`
