I am not sure if this is the correct process but as I understand it, this is my solution:
Since Jane is 6 years old and she is twice as old as her brother. Which means Jane's brother is 3 years old.
brother = x
Jane = 2x
2x = 6
x= 3
Now, we need to solve for the year/s needed for Jane to be one and half times older than his brother:
years = x
Jane = 6
brother = 3
1.5 ( 3 + x) = 6 + x
4.5 + 1.5x = 6+ x
1.5 x - x = 6 - 4.5
.5x = 1.5
x = 3
Therefore, Jane is 9 (6+3) and her brother is 6 ( 3+3).
Is this correct??
