Shobo's mother's present age is six times Shobo's present age. Shobo's age five
andre [41]

Shobo's age = x years

His mother's age = 6 times of Shobo's age

= 6x years

Five years from now

________________

Shobo's age = ( x + 5 ) years

According to the problem given,

x + 5 = one by third of his mother's

present age

x + 5 = 6x / 3

x + 5 = 2x

5 = 2x - x

5 = x

Therefore ,

Shobo's present age = x = 5 years

His mother's age = 6x

= 6 × 5

= 30 years

A number increased by four is the same as 19 minus 2 times the number
LekaFEV [45]

From the information given, 4 added to the unknown number is equal to 2 times the unknown number when it is subtracted from 19.

Let the number be x

x + 4 = 19 - 2 (x)

We now expand and simplify the equation by placing unknown on one side and the known on the other side

x + 4 = 19 - 2x

x + 2x  = 19 - 4

       3x = 15

         x = 15 /3

          x = 5
