Answer:
Step-by-step explanation:
Let her present age = X
Her age 3years ago=x-3
Her age 5years from now = X+5
Therefore,
1/(X-3) +1/(X+5) = 1/3
(X+5+X-3)/(X-3)(X+5)=1/3
(2X+2)/(x²+2x-15)=1/3
3(2X+2)= X²+2X-15
6X+6= X²+2X-15
X²-4X-21=0
X²-7X+3X-21=0
X(X-7)+3(X-7)=0
(X-7)(X+3)=0
X=7 or -3
Therefore her present age =7
Hope it helps you!!!!!
May God bless the hands who mark it as brainliest answer !!!
