Answer 1

Answer:

Step-by-step explanation:

Aman. son

3x. X

3x-10. X-10

5(x-10)=3x-10

5x-50=3x-10

5x-3x=50-10

2x=40

X=20

Answer 2

Step-by-step explanation:

let Aman's son's age be x  then Aman's age will be 3x

Ten years ago-

   3x - 10 = 5(x - 10)

=>3x - 10 = 5x - 50

Transpose 50 to the left and 3x to the right

=>50 - 10 = 5x - 3x

=>   40     =     2x

Interchange the sides

=>    2x    =     40

=>     x     =   40/2

=>     x     =    20

Therefore Aman's age = 3x = 3 x 20 = 60
