Let S = Suzanne's age now
:
Write an equation for each statement:
:
"Chanda is now four times old as her sister Suzanne."
C = 4S
;
"Next year, Chanda's age will be three times Suzanne's age then."
C + 1 = 3(S + 1)
:
C + 1 = 3S + 3
:
C = 3S + 3 - 1
:
C = 3S + 2
:
How old is each now?
:
From the 1st equation substitute 4S for C in the above equation
4S = 3S + 2
:
4S - 3S = 2
:
S = 2 yrs is Suzanne's age now
:
You figure out C's age
