age problem (math)
posted by HELP HELP HELP MNHS .
Nila is now x years old. 3 years ago, her brother ricky was twice as old as she. Write ricky's age 10 years from now in terms of x.
(with solution pls... thanks...)

Three years ago:
Nila's age  x3
Ricky's age  2(x3)
present:
Nila:  x
Ricky  2(x3) + 3 = 2x 6 + 3 = 2x  3
in 10 years:
Nila  x+10
ricky  2x3+10 = 2x + 7
