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