f(x) = -10

Add 1 to both sides:

-9 = -x

Divide both sides by -1:

x = 9

Abigail is 8 years older than Cynthia.Twenty years ago Abigail was three times as old as Cynthia.How old is each now?

xz_007 [3.2K]

Let
C=Cynthia's age today
A=Abigail's age today

then
at all times
A=C+8......................(1)
twenty years ago,
A-20=3(C-20)
simplifying
A=3C-40...................(2)

Equate (1) and (2),
C+8=3C-40
8+40=3C-C
C=24
=>
A=32

Check: A-C=8... ok A-20=12 C-20=4 => (A-20)=3(C-20) ...ok

Answer:
Abigail is 32, Cynthia is 24.
